Create Widescreen View - Index | Pager

[hanzyd]

• What does this PR do?

This example is a proof of concept for "Show index and body of emails in a horizontal split (side-by-side) #1250"

This is not really intended for merge, but could be used as a base for someone which will like to complete this, I think.
I think that I managed windows layout correctly, but they are few places in the index window management where probably better fixes are needed. These are places where index in minimised when pager have to be shown. Also space allocated for the pager is permanently visible. Side-by-side layout is controlled by option 'pager_columns', which more or less overwrite 'pager_index_lines'.

• Screenshots (if relevant)

• What are the relevant issue numbers?

Fixes #1250

Well done for creating this, @hanzyd.

I had a go myself last year: https://github.com/neomutt/neomutt-old#neomutt-2020-09-25
But then, and now, I didn't have the time to develop it.

The big problem I wanted to understand was about 'dividers'.
Who owned them? Who was responsible for drawing them?
Should the Window code be creating them automatically?

a base for someone which will like to complete this, I think.

and there's the problem. We have lots of ideas, but few people to implement them.

You've done a great job creating this PR -- the NeoMutt code can be hard to understand!
Have you got some time to work on it?

I'm always happy to mentor new NeoMutt coders ❤️

If you have any questions, feel free to ask them here,
or join us on IRC: #neomuttt on irc.freenode.net (web client)

Thanks!

Thanks! What I am not sure now is that widescreen mode is better than existing one. I mean, to be able to see more from the subject line I have to trim the date and time columns. Even after that subject line is badly trimmed.

I see that my attempt solving this is more or less the same what you have done.

I'll think a little about how the index visualisation could be optimised, and maybe I'll come back later.

Thanks for the help offered!
