[Feature Request] Turn off commit numbers or toggle side panels to make more room for side by side diff

I am sorry if this is already possible, but I am new to lazygit, and it is amazing!

I am using delta side by side view and have reduced the width of the side panel. I do want to know the names of the commits, but have no interest in the numbers, that is just noise. How can I remove the numbers so I have space to read the names? Maybe I could toggle the entire side panel on and off?
```
gui:
sidePanelWidth: 0.2 # gives you more space to show things side-by-side

git:
paging:
colorArg: always
pager: delta --dark --paging=never
```
