Great man.. Love the FPE editor.
1. I would remove the Verticle scrollbar in the Main Window, and make all windows to fit the Main Window Frame
2. I still work in 1366 x768 resolution size, and when manual resize the asset library window my verticle scrollbar disappear and not
all info display. (see attached ss)
3. The search window popup right aligned, which make the list with results (when resize the window) disappear on the right side
and you manually have to move the window (see attached screenshot). May center the window if possible.
4. Scrollbar on search to indicate activity...
Personally, when I design, I center all my windows, but if the user move / resize the window I store that x/y values in a INI file, and next time on load, I use that values to display the window.
I never use a verticle scrollbar on the Main Frame as default, and try all windows to fit inside the main frame.
If the user want to drag/resize the window bigger than the frame, the I show the scrollbar.
But this is a personal taste.
Great Job Man, keep it going....
