1-2-3-4-5 keys, expand active pane on the second tap

[slavshik]

Is your feature request related to a problem? Please describe.
I use hotkeys 1-5 to focus on a pane right after I launch lazygit. I find it very handy and thank you for that ❤️
But I would like to request the ability to switch and focus on a pane using a single key pressed twice.

Describe the solution you'd like
Currently, I use the following hotkeys to focus on a specific pane:

• 3 to focus on branches;
• 4 to focus on logs;
• 5 for stashes.

However, when working on a small monitor, I often need to expand the focused pane (Shift + =) right after the focus action, like 4 to focus on the log, press and hold Shift then + or ++ to enlarge the pane. I think it would be handy to add a second tab handler, like:

• 5 to open stashes and 5 again to expand the pane;
• or 4+4+4 to open logs in fullscreen right after I've launched lazygit.

Describe alternatives you've considered
Add Shift + <1-5> to focus on an expanded pane.

The suggested solution (pressing 4 on the pane under 4 again just expands it) seems reasonable and simple, at least at a first glance.

Add Shift + <1-5> to focus on an expanded pane.

How would that work when you're in a zoomed in pane and press shift+<some-other-pane>? Do you just switch to it, without changing the zoom level, or do you both switch and zoom in another level?

I'm against this idea because I imagine that some users have keybinding combos memorised where they need to do commit from the files panel so they press 5+c, and I don't like that if those users are coincidentally already in the files panel that it then has a different effect.

Open to getting more people's perspectives on this

I'm not familiar with the code, so I don't know if this is possible, but you could have a double tap of 4-4 be the required input for fullscreen logs regardless of whether the window is open already. But that would require detection of a double tap in quick succession, and I don't know if that's something that is or should be supported.
Then the 5+c example would not break regardless of being on that panel or not.

I am waiting for any alternative that works. Sometimes I really need to expand the Files panel because list of unstaged files is too big....

[stefanhaller]

@dejlek How about pressing +? That's what it is for. (It also makes the diff view narrower, which may not be what you want.)

Personally I'm pretty happy with

gui:
  expandFocusedSidePanel: true
  expandedSidePanelWeight: 3

@stefanhaller OMG, that is it! Thanks! :) Also, when I pressed + again it went full-screen mode. Perfect!

Since this issue was created, we have chosen to give the option to do repeated taps of 1 to cycle through the available tabs,
#3794 and Jesse's message from 2023 proved quite prescient

I don't like that if those users are coincidentally already in the files panel that it then has a different effect.

as we then had many annoyed users #3927 but also many other users that really like the feature #4288 (comment)

Either way, we don't need to overload multiple number taps more 😅, and we have the config Stefan posted above to help small screen users.
