By default I prefer the "Full Screen Mode with Menu Bar" (under View->Screen Mode) because it's a free canvas/ or allows for a more customized interface.
THE ISSUE IS: that upon entering this Screen Mode, your file tabs disappear (guess its not included in your "Menu Bar"), and often I'm working on multiple files when it comes to CG textures or kit-bashing assets from multiple files for a concept.
(Example: I made a psd full of Halftone patterns/folders/groups which I drag & drop into other psd's/concept pieces/CG Textures)
This is a small thing, I know, but it would be great to not feel punished for wanting a free canvas.
Really appreciate the hard work programmers,Cant wait to see next update
