It would not work for certain cases, you’re right, like stuff with many differnelty names documents or doing research in the browser.

But for what I had in mind - I’ve checked and on my setup the projects name is in the apps window decoration, in the cli when I do the commits, in the directory view sidebar, in the OS taskbar etc.

It should be pretty straight forward to figure out from a screenshot, even when the app is not in the foreground.
