Pane/Window management like in Vim

[Rosbifbr]

Hello! First of all, I would like to congratulate you all on the seamlessness of this editor. The particular performance and usability of the buffer editor in vim mode is really amazing.

However, when using the Vim bindings, I do perceive a very significant "breakdown" in usability when navigating in panes which are not buffers, such as the AI completions tab or the file explorer tab. In short, while the buffer editor is Vim-like, the other panes are impossible to navigate in a Vim-like way. Not even closing, reordering or splitting those panes works, so when I want to close the AI chat window for instance, I have to use its special shortcut, not simply Ctrl-w+c

In regular Vim one would expect to be able to manipulate and move these different windows similarly, because deep down they are buffers/panes. This current state of affairs hampers usability by making users work in Vim-like mode when editing text, and then switching to a more Vscode-like workflow when messing with these auxiliary tabs. It does not work very well and in practice you have to memorize two semantically unalligned keymaps. One for the buffers, one for the special panes/tabs.
