> tmux+vim is as good as your Visual Studio.

You probably don't need tmux. The utility is really when you're remoting into machines and want to keep your session (or are too lazy to use nohup or disown)

Your terminal should split panes for and do tabs. Ghostty is my preferred but use whatever. And fwiw, even if your terminal sucks vim can do this all for you too (:term), so you don't even need to leave vim.

FTFY ;)

Side note: just because you can live in the terminal on Linux doesn't mean GUIs can't exist or are even second class citizens. The real beauty is being able to have both. You can have a platform that is usable for most people while not fucking over power users. Wild concept, I know
