 Let's see how activities work. Well, to know how they work, we first need to create one of them. So let's go to the activity switcher and then click on create a new activity. You will see the list of all open activities to the left. We can choose an icon, pretty much any spine, and then a name, which should be descriptive, such as example. And we can also set a shortcut to switch to that activity immediately, otherwise just meta tab or meta shift tab by default. And we can also set a privacy level if you maybe don't want your current errors clicks to be saved because current error saves what element you click so that the next time you do the same search, it gets pushed at the top. Of course, nothing is shared with KD by default, that's obvious. But anyway, let's click it, why not, and then create a new activity. And when you do this, you will see that it will be added to the list of the activities. And we might want to switch between them, we can just click on them, but another way is to use meta tab, and yet another way is to use the widgets. There are three of them. The first one is just activity, it's the one that I use the most, it tells us what activity we are in and the list of activities when you click on it. The second one is actually a tab bar of all activities, and you just have to click between them to switch, pretty easy. And the last one is actually the virtual desktop one, it's like the virtual desktop one, we can see all activities which between them just by clicking, and we can also see if there are window open and so on. So that said, we can try to switch to our default activity, and then let's, we can actually start using them. As an example, we might want to organize a task, say we need that desktop instance, maybe we want to work on this init.py file, and we need to do some work with it, let's open it with gate. So to do this, we can either use it here among other windows, or we could just bring them both to another activity to make the work a bit more organized and less prone to distractions as well. So let's see how to move Dolphin to another activity. Just open the left sidebar, and then drag Dolphin from the task manager to the activity. And that's it. Then let's switch to that activity, and as you can see, we have Dolphin. Another feature is to be able to save a desktop configuration for each activity. As an example, we can change the wallpaper. Let's maybe pick something pretty, let's see what I've got. These are all of the wallpapers. Let's actually go with shell because I like it. And then we can actually have this wallpaper to be in this activity, and another activity will have its own wallpaper. We can also add widgets. As an example, let's pick the clock one. And then this widget, this activity, sorry, we'll have this widget and another activity can have other widgets. So we can see that we have our web, our activity wallpaper, our activity widget, and our activity windows. So you can stay organized with our task. As an example, one thing that I used to do a bit ago was to actually use a widget that is called GitLab Issues, if I remember correctly, by Zeyran, which is super useful. And I linked it to the KDE GitLab account so that I actually received all of the issues and mostly pull requests, and it was very useful. But of course, I only needed it for the KDE activity. So I just put it here in the background of the KDE activity. So when I switched back to the default one or maybe to the school one, it disappeared. And activities really are about organizing the work. I've got my school one with the lessons I need to watch or the default one, but also the Python one with the scripts that I'm writing and so on. And one of the most beautiful, I think, feature is the ability to actually stop an activity. Maybe you're like giving it a pose. You're not longer working on it. As an example, I'm not studying. I'm not using this example activity, nor I'm writing Python ones so I can just stop them. I actually need to close the Dolphin dialogue before closing the Python one. And then those activity will be just removed from RAM. The application will be closed, but their state will be remembered, which means that just by clicking them, we can bring back all of the windows where we left them at the position and the settings and so on as we were working with them. It works just perfectly with first party apps. It works okay-ish with some trouble sometimes with third party apps. As you can see, Dolphin was restored exactly as we had put it before, so flawless. Another useful feature is in the favorites, so in kickoff. And basically, if you have an application that you only use in one activity, as an example, KDE Live to me is of course only used in the KDE activity because that's in the activity I do videos on. I can just take KDE Live, right click and add it to the favorites, but only to this activity or any other really. You can also select multiple activities, which means that when I open up kickoff, I will have KDE Live in the KDE activity, but I actually won't have it in the default activity, it will be just disappear. So I can switch between them and the favorite apps in kickoff will adapt to what I'm doing right now. Then there's another feature that it's not 100% supported, so maybe you don't use it, but if you need to, here it is, right click on a file and then select link this file to this activity or any other activity as before. This will basically tell the activity. This is a file that I very much often use when using this activity or any other activity. And in practice, this means that we can go to the URL activities, activities column and that's it. You can see all of the open activities and if we click on the current one, you can see all the files linked to our current activity. Another way to put it is to actually go to add a new widget, which shall be the folder view and then in the settings of the folder view, select as a custom directory activities colon slash current slash and this will make the folder view always show the files that you should be working on or that are related to the activity you are in. So this one is also pretty useful. I will also show you the settings of the activities. There's pretty much the stuff we talked about earlier. And then that's almost it. One more thing is that you can right click on the title bar of a window and then select show in activities to make a window appear in one or more activities. As an example, if I don't know any telegram to be many activities at the same time and just right click the title bar, select the activities and select all of them. And it will be there regardless of what activity I'm using. Finally, one last thing you should look into is customizing the task manager. You can actually choose whether to show the icons from this activity or all activities. If you show the icons from all activities that will make it a bit easier to switch between them, maybe you have this application, this activity, another application, another activity and you just click and switch between the activities as well. But maybe it's also better to also keep it just from this activity so that you don't get a messy panel with lots of icons in different activities because the whole purpose was to get organized. And that's pretty much it. I hope that you better understood activities and that this video was useful. Bye, bye.
