sounds good. maybe we don't even need the tooltip? in practice just the 
starting bit (as wide as the thumbnail itself) would be enough?

ew.. maybe on mouse over? but certainly not as a default. i can just imagine 
the visual effect of having 3 or more dancing strings :)

yes, i can't really touch the current code i don't think. it would be a 
behaviour change. but we can at least mark that as deprecated and move forward 
from there.

void activate(const KUrl &); // the common, easy case
void activated(cost KUrl &, Qt::MouseButton, Qt::ModifierKey);

it's not overly difficult; if you're up for it, i can help you through it e.g. 
on irc ... if not, i can try and work this part out for you.

yes, it should be added there ...
