How to change VIM cursor shape while in different modes in Gnome Terminal
I tried making GNOME Terminal vim mimic GVim's default behavior of using a white block for command mode and a vertical pipe (aka I beam) for insert mode by following instructions this post, but the system doesn't work particularly well with tmux and multiple terminal vims being open.
I don't want to give up just yet, so at the very least I would like to have some indication of what mode I'm in. I read somewhere that old-school vim users used to have some trick for it, but I can't quite find it. Something about highlighting.
Any help would be appreciated.
