suggestion. I'll look into this a little more.

but I could live with that. What I've noticed is that using CtrlP and
jumping to a tag tends to put my cursor all over the place when
jumping to another buffer. I wonder if that's because the tag is
within the visible data at that point, so Vim doesn't scroll? I'll
have to investigate that more.
