I would like to take a program I use in Windows 10 (Q-Dir, not that it should matter) and dock it to a screen edge or corner, so that it is normally hidden and only pops into view when the cursor hits that screen edges in contact, and hides again when the cursor leaves the window - basically a lot like the taskbar when set to auto-hide.
Is there any existing software that will do this? Preferably something that can just perform this task (i.e. not something drastic like a desktop replacement), and preferably not something clumsily using AutoHotkey or similar.
Writing my own satisfactory solution with AHK is an acceptable fallback, but I'd rather not spend the weekend writing something robust enough to comfortably handle evolving use yet still unable to hook appropriate control options into titlebar context menus.
It's not a big deal if the program also insists on stretching the winow along the whole length of a screen edge, but it needs to at least let the other dimension retain original size.
