Are there any plans for changes on ContainerWindows (floating windows)? Currently they are very bad. Icons are way too small. Although this seems to have been caught in the Editor UI redesign thread, so it might finally get fixed. They don't exist as true, operating system level windows. This comes with it's own set of problems: They can't be truly maximized. The maximization button only makes the window size equal to the screen's: the window can still be moved after this and it can't be restored; They can't be minimized; You can't Alt+Tab between these windows and the editor. The problems above are just the tip of the iceberg, as the conjunction of all of them even allows you to sometimes simply lose a window. Like this: I have a lot of opinions about this topic, so if there is any interest in it, I can try and write some more about it. What I really want in the long term is basically the same funcionality UE4 has in respect to this: webbrowser-like tabs and something like a "CustomContainerWindow" context. These would allow for some more complex workflows which require lots of windows to be MUCH more feasible in Unity.
