Just wondering since I know a lot of people quietly use a screen-area-select -> tesseract OCR -> clipboard shortcut.
I separate subjects of interest into different Firefox windows, in different workspaces -- so I have an extension title them and a startup script parse text to ask the compositor to put them in the correct workspace (lets me restart more conveniently).
I have automatically-set different-orientation wallpapers for using my 2-in-1 depending on whether I use it in portrait or landscape (kind of just for looks, but I don't think if anyone else adds a wallpaper change to their screen rotation keybind).
There is a toggle for SFW/Sketchy which in my experience has worked pretty well in avoiding such things, but you are probably right it does not catch everything.
If such a thing happened, I would just re-run the same command to update to a different one though. I guess I generally just make sure no one is in the room when it runs haha.
