Configure Pane Frames

[a-kenji]

Allow the configuration of pane frames.

For example where or whether to show the scroll indicator. Have some right aligned, some left aligned. Display the information at the bottom of the frames.

The current default configuration could be something akin to this:

pane_frames:
  top:
    left: [title, ]
    right: [scroll, ]
 bottom:
   left: []
   right: []

Allow the configuration of pane frames to depend on the mode they are in.

Hi, I would like to start this issue.

Currently, the configuration of pane frames is global and can only be enabled or disabled by options 'no-pane-frames'. Maintaining this behavior, @a-kenji 's suggestion would also be global and would only affect the title and scroll. I think it's good that we start like this and then we can expand later. Maybe adding custom settings by tabs or affecting plugins too.

What do you think? Any suggestions for a-kenji's template?

@oromate,
that is awesome!

global and would only affect the title and scroll

I agree! Though keeping in mind extensibility for other "providers" would already be good. Something similar to scroll and title.

It is enough if it is a global option for now.

We can think about different extensibility at some point.
I like where you are going with this - I too think it would be awesome to have plugins configure the pane frames themselves, or for example have a callback so that we
know if a certain section is getting a mouse event.

Any suggestions for a-kenji's template?

Of course I am open for more suggestions.
We also want to display a name for a pane, similar to the tabs in the pane frame,
if you keep that in mind while working on this pr, that would be great.
But obviously not a prerequisite.
