feature: vertical header

[adrianinsaval]

It would be nice if it was possible to have something similar as the -H option but vertically where the set amount of characters are ignored for selection and horizontal scrolling, a common use case would be bat's line number column

Thank you for Issue.

I don't think it's more convenient than expected, so now it's reluctant to implement.

I think it is better not to display the row number of the bat when using the pager.
That's why I need other reasons to be used.

[adrianinsaval]

bat's line number column can also display git status not just line number so it can be useful to display it

[adrianinsaval]

it might also make sense to allow using a delimiter regex instead of character count since the column grows if the file has >9999 lines

[noborus]

Good point, but I wonder if it is really that inconvenient that it only becomes invisible
when scrolling to the right without line wrapping.
Additionally, there is the drawback that the fixed-width display area on the left becomes narrower.
If we were to implement this, I believe it would be necessary to have a very easy way to toggle it on and off.

mainly what I would want is that the column is ignored for selection and therefore copying
