That's my main issue with terminal emulators. Why can't I click anywhere to put a cursor in there? Why can't I delete a selected text? Some hotkeys work as expected (e.g. Ctrl+Delete), but others don't (e.g. Ctrl+Backspace). Those are simple things from a user standpoint. Terminal could be so much more usable. I'm not even talking about integrating real GUI into terminal, for example pressing Tab should open dropdown list, not emulate it with text.
