Add an option to pin specific sections (e.g., files, branches) as always open, even when Lazygit is in accordion mode due to a small terminal window. This prevents users from accidentally committing to the wrong branch.
### Is your feature request related to a problem? Please describe. I sometimes have a small terminal with Lazygit open to the side. When it gets very narrow, it collapses into accordion mode, as per [this issue](https://github.com/jesseduffield/lazygit/issues/440). However, if I have the files section open, I don't see what branch I'm on, leading to making changes, even committing and pushing to the wrong branch. ### Describe the solution you'd like I would like an option to pin sections (like status) as open when using small accordion window, so I can see the branch name at the top. ### Describe alternatives you've considered If not pinning a section open, then maybe just an option to pin branch info (or any info) somewhere.
