Feature proposal: TUI drop-down menus about micro

[Andriamanitra]

Hierarchical dropdown menus are rather clunky to navigate without a mouse but something a bit simpler such as showing a list of available filetypes when the "ft:unknown" is clicked would be a nice touch. I'm not sure how the implementation would work though considering the statusline string is completely customizable through statusformatl and statusformatr settings.

This is a bit ambitious for now I think (especially making the statusline interactive, for reasons explained by @Andriamanitra). However, I also think that providing a plugin API for drawing on top of the buffers might not be too crazy of an idea.

I have implemented something experimental in that vein in my personal fork (although I have only done a couple things with it), so I have an idea of how it could be done -- the problem is that, at this point, it is wiser to lessen the maintenance burden on micro, so I am hesitant to start work on this.

Also, I wouldn't want to push for this without blessing from the maintainers and the wider community. Are features like this even something we want to complicate micro with?
