Use case or problem
When using the built-in vim bindings, :q, :wq and :x does not behave like in other text editors/IDEs. Ideally, it should exist as an option to let us close tabs more seamlessly especially for those used to vim motions. Adding command mode options to switch between tabs as well would be a welcome change.
Proposed solution
Add said vim bindings. It would make the built-in vim bindings nicer to work with, although it currently constitutes quite a good vim emulation already.
Current workaround (optional)
In theory, it is possible to remap commands with the Vimrc support plugin.
