Got it.

Seems like tooltips are handy but can be a headache maintaining as there 
is variability in systems and toolkits. A similar thread which I started 
on the Yoshimi mailing (Yoshimi uses FLTK so a different toolkit) seems 
to raise similar "it's complicated" reactions.

Food for thought, as I'm not sure what kind of UX could replace or 
integrate tooltips.

One idea might be some sort of dynamic 'status bar' or similar UI like 
in web browsers where the target url is shown when you hover a 
hyperlink. Actually it seems in most browsers the 'fixed' status bar was 
removed and a sort of dynamic UI elemetns which hovers the widow is shown.

Considering that Rosegarden does have a (hide-able) status bare which is 
empty when the knobs are hovered this might be a place to have that 
info? Also I see the kind of message as analogous to what appears in the 
status bar when for example you hover tracks in the main view...
Just an idea which came to my mind.
