I think it would be neat if you could set splits that are equal to your golds as a certain color in the delta column. Is there a way to do this?

where exactly? wsplit? livesplit? splits.io? the specific integration of splits.io on here? another split program?

Um.. all of 'em!

I haven't heard of this existing, which I can see might be the case because human splits are inaccurate, and you're almost never going to get the same time down to the millisecond. If someone coded for a range of values, though, it could hypothetically work.
