mapping to toggle two layouts / pick a layout to disable

There's a layout I never use: the "half" layout. \
I always skip over it in my usage; I would like to have an ability to *just* toggle between the normal and fullscreen layout. \
This can either be achieved with a mappable action called something like "toggle fullscreen" \
or via a setting called "disabled_layouts" where you could specify layout(s) that you would want to disable. \
I guess only disabling one layout makes any sense though.

Currently I take direction into consideration, when using `+`/`_`, to skip the half layout \
While this works technically, I don't want the half layout to begin with, so I would love to be able to express "go to the other layout I want" more directly.

I did a quick search of the issues, and didn't find this. I'm sorry if this was already discussed and I missed it. \
I was hoping to use a custom command for this instead, but it seems like they are for shell commands specifically, not interacting with lazygit's ui.
