I use it all the time as a temporary scratchpad or clipboard. It opens very quickly, it doesn’t have anything else other than a text area. Not sure what else should I use :) VSC? Opens too slow. Sticky notes? Not sure, slow and too complex for the task. Also it’s an advantage that it doesn’t save the state anywhere so I can just force quit and everything disappears.
I am missing Paint and Notepad on MacOS when I just need something that opens in a millisecond and I can paste in something temporarily.
