Started up Warp Terminal once again to check out the latest updated. The various displays in Neovim all look correct now, which is great. And the notifications on finishing of long-running commands is welcome, since I'm frequently running long tasks in other tabs at work.
They've also added a quick session switcher (Cmd+Shift+P). Still would be nice to be able to switch between entire sets of tabs, like tmux lets you do, but I'm ready to give it another serious try.
