 Yeah, hi everyone. I'm Julius and I'm going to talk a little bit about the theming app as this was the first part where I contributed into the next cloud. And yeah in the past there was always this theming thing but there were PHP classes which you had to change and it was always this thing that this themes broke after an update or you had to actively watch what's going on with the theming and what's with the theming app in the next cloud is that it's basically always in there and we have this simple form where you can just fill out some basic values and even after updates those theming should work and yeah for now this always works and yeah the key point is we really want to keep this simple we often have this request for different icons for yeah every position in the UI but as you can see there's basically only one logo and the login image and yeah it's always kind of fun playing around with this as you can see this was at the hack week and right in the last months that's already also where I started contributing was doing some small fixes in the UI elements adding the logos right like there in the sharing button or Lucas did some performance improvements with rendering the image smaller and so this theming is basically in most places and next cloud but there are some things missing it's this basically all the icons and this is what I'm currently working on but there's yeah the support for S4G images is still not that good as it should be so yeah I created this dynamic creation so we can create colored icons for the folders or for mime types for different mime types and we can also generate fuff icons depending on the color or the app icon or even if you upload a custom instance logo you can then get the fuff icon with this logo so this is what's coming I guess with next cloud 11 when we get this ready yes and we have this capabilities API where the theming values are also in so any client developer can now ask the server what is the color used so clients can also like the Android app is already doing this for the background image I guess or it's coming so clients can also use those theming values and yeah I'm always thinking about how we can go further maybe a plain background image or something uses one because those yeah photo is always taking some time to load and maybe with someone some people don't want it or yeah maybe custom CSS but that's a little bit against that simplicity that we have now and we also have some features for app developers like we have CSS classes to apply the theming colors to your apps or we have this JavaScript object like in some apps you have some special cases like the notifications app had this little well icon in the menu bar and then of course you need to check is there a dark background or is it a light background and therefore you can use this JavaScript object but I guess the most important thing for app developers is to just use as much native UI elements as possible and don't try to mess up too much with your own styles yeah and I'm always welcome for any hints ideas for the theming app and thanks
