This, though I've always found the Chrome/Firefox vimlike browser plugins to be such second class citizens that they've never stuck with me.

I used to use modal tiling window managers on Linux, but since window managers are always second class on Mac/Windows, that never stuck either. I bounce around too frequently for it to work. I just suffice with tmux for now.

I was pleasantly surprised to find Discord's `s/search/replace` supported as an actual feature, though having it limited to just the last message is a bit limiting.

I've had a good experience with Tridactyl on Firefox, but yeah, definitely second class citizens.
