Thanks for the recommendations! Since switching from Kubuntu to Ubuntu, I have been looking for a replacement for Konsole and had finally settled on Terminator, but one major gripe I have with it is searching the scrollback, which is a bit buggy (results aren't highlighted, search is case sensitive even though it's not supposed to be). I just tried Wezterm and it seems to tick all the boxes. Now I just have to figure out how to configure it, seems a bit more complicated than most other terminal emulators...
