Since weeks the new Version 6.4 is available. Yesterday I've installed the new version, and I was shocked. Very very tiny Icons, and not logical arranged anymore. In the 6.3.x Version all Icons are big enough for 2540x1440, now with the new Version 6.4.x my eyes get hurt. The Icon arrangement in the 6.3.x was nearly perfect in PCB Mode: Photo View -> Autorouter -> Gerber ... one Workflow Line, perfect. Now in PCB Mode, the Icons are so tiny, and Photo View "Left" ... then a lot of empty space, then Autorouter "Right, and Gerber again "Left" This is complicated, back and forth and back, and the space between very very very large, and very very very tiny Icons. And... the Icons are not resizable, and the Icons are not arrangeable. So I have to use  the 6.3.x version in the next month, for a good workflow.
