Oh, I didn't know it. It looks pretty useful, but it requires more mouse usage than I'd like and its window is not very well suited for tiled window managers straight out of the box.
Yeah I have a rule in my i3 config so it gets focused and fullscreen. It does require mouse usage, which is why I wonder why I like it over say, lazygit. I may switch, but yeah, thought one should know of its existence, it is a cool piece of software, too.
But the main use I get from it is for incremental index adding, so maybe not as much as OP.
