Love all the terminal tooling that's come out in recent years. I'm this close to chrome and rofi being the only gui I'm using on my work machine. This looks great!
There's some stellar libraries in Go for terminal stuff, in particular anything from charmcli. They have an elm style TUI framework called bubbletea (which superfile uses), a styling library, prebuilt components, it's really incredible. I'm building a multiplayer tetris you can play through ssh, which is using bubbletea and another lib of theirs called wish.
they have a lot of stuff you can just use in regular shell stuff too: https://charm.sh
