It’s the opposite - I use the out of the box settings for serious work - it’s
the unserious playing around that I try to speed up.
I’ve said on several occasions that I’m indifferent deactivating some or all of
vertical skylines as a default. Several people are against this deactivation
(notable Janek). I’d be interested in gradations of UI options called perhaps:
\faster-but-uglier
\a-lot-faster-but-a-lot-uglier
\ridiculously-fast-and-heinously-ugly
that people can invoke at the top level to speed things up but get uglier
results. This is trivial to implement, but I’d be interested to hear what
UI-savvy people think.
Cheers,
MS
