That was actually what I ended up doing too.....but then I miss having tabs and go back to the system terminal, and Allacrity explicitly doesn't want tabs. Argh. It's all so anoying.

Yeah, I use my window manager for the tabs. They are very necessary, but I like it better when the WM does it instead of every app. You'd be surprised how often you want to have your browser and terminal tabbed together in the same window once it's an option. Plus, you don't have to remember ever app's tabbing hotkeys.

Why not use tmux for tabbing?
