That should be shown on the ruler's tab.

I will disable that. It was supposed to be used for control rulers over
"other" properties than velocity (turned out there isn't any yet).

Can't tell without looking at that API, but even though the current control
ruler code is somewhat abstracted from the data it handles (see
ElementAdapter class in controlruler.cpp), it does rely on Elements being
there.

The X axis should be in the middle of the ruler in such cases...

Of course, there's a minimum height.

No specific idea, that's just pref saving.

Given what remains for 1.0 and the amount of work this is likely to take, I'd
say out.
