The time line now shows "ghost keyframes" from the last tool you selected. It makes timing between different tools a lot easier when animating.
The evening yesterday I got the idea of replacing the figure layer list in drawing tool with the Elemento drawing nodes. I think it makes it easier to understand which layer one draws on. You can also move the layers up and down, which is a lot easier than using Zorder in Edit Fonts & Colors.
You might think that this opens up the possibility to animate each element individually. You are right, this is one of the reasons I'm doing this. The good thing is, that nodes with expressions will not be animated, so one can have amazingly control over the animation without doing too much work.
I liked specially that you can hide the figure without adding a key frame in switch tool. The design could be more compressed using icons, but it is better to take small steps than ending up with a design that does not work.
