I find myself slightly frustrated with the editor layout in advanced mode.
I find I don’t use the entities panel or the world tree panel very often, and spend a lot of my time looking at the game viewport, and the code editor. However, the panels I use the least take up ~25% of the screen or more.
I’d be interested in a slightly modified layout that reduces the space used by those panels.
Here’s a really crude mockup that shows what I mean.
The editor takes up a good 50% of the screen here, while the game port takes up most of the other half, with the remaining deadspace (since the viewport is 16:9) taken up by the other panels.
