Im using what DE provides by default. If You do not know what You need from terminal that means You probably do not need anything more. Make a switch when You want something particular. On the other note I think You might be more interested in different shell rather than terminal. So fir example zsh or fish (You are most likely currently using bash)


You can just stay with the last plasma version that supports x11 as long as it doesnt start to bit rot. Btw, try wayland and see if YOUR workflow works
