using zed more and more to develop zed itself I'm finding some small qol
features missing, this is one of them
I'm very used to open two or three splits, and sometimes I want to close
everything except for the active editor, but that wasn't supported, as
the `pane::CloseInactiveItems` action only closes inactive items on the
active pane
so I've implemented it really quick, although I'm not sure it's the
right way to do this
note: I really don't like the default keybinding I've set it to, I have
this action bound to `cmd-shift-w` on all editors, but in zed is taken,
so I chose something that's free but without thinking too much about it
Release Notes:
- Added action for closing inactive editors from all panes
