I'm trying figure out how far I can go in fine-tuning the appearance of my Vim GUI. I'm using MacVim 7.3 and what I'd like to do is change the padding, text-alignment and border color of the line numbers.
I know there are some standard configuration parameters in the highlight command, particularly the gui group, but what if I want something beyond what's offered there? For example, a right border as opposed to underline. Is this possible?
It could be that it's simply not worth the trouble, but I'd like to at least know what the initial steps would be so I can make the call. (Even if it's just :help adding-border-to-line-numbers and I happened to miss it).
Thanks.
