Qutebrowser: Command titles in the keybinding contexts

[Chinggis6]

It is a feature request.

I have a lot of my own key bindings and I sort them under contexts.

For example I have a separate context for Wikipedia and Video (mpv player), as seen below.

I'd like, when binding, to additionaly (perhaps with bind --title "", as an _optional switch_) put my titles (or tooltips) for the commands binded, so it's more user-friendly and easier to read, understand the function of, and remember.

It's especially useful when binding verbose commands into a key, or when userscripts are involved.

I think, it should be an optional feature for the context, and might be implemented as the middle column of the tabular context which can be empty.

Thanks for the consideration.

cc @rcorre - probably one for after the config revolution though.

yep, probably best for after #499. Which I actually want to look at after #74. Which is coming soon! For real this time!

@Chinggis6, In the UI, would you expect the title to come before/after the action, or to replace the action text entirely? In other words, would you expect Vv spawn mpv {url} Open in mpv or Vv Open in MPV? I'm thinking the latter because it is easier to read at a glance.

I also think the text alone would suffice - and we could also provide a neat default text for the default bindings.

I'd sure appreciate a bit of help with #499, but we need to carefully coordinate that - please join the IRC channel first and let's discuss before you start any work on that :wink:

just a note - it would be preferable for the title not to be mandatory :)
