Awesome!

One other thing, not about this PR, but while we're talking UI: the 'insert table' dialog is not really usable for me, because it's not really scaling well and somehow is much too small. I can't rescale it manually, I think.

Do you know how to fix that? (Not necessarily for this PR, but I looked at it a while ago and couldn't find an easy solution)
