Even better, I just looked and found out that there are some half-decent 
*standard* icons included with KDE. Really shows how much effort I've put 
into the edit panel so far really :-)

Ok, I'll add in support for the icons in the next couple of days, as soon as 
I've tracked down the crash-on-exit bug in Kdenlive.

Hmm... fair enough, though from the GUI's point of view, the format does not 
matter.

The class GenTime in Kdenlive is a generic time class to allow you to perform 
operations on time without worrying about converting between various formats. 
E.g. you could add  65 frames at 20 frames per second to 3.612 seconds, and 
then find out how many frames that would be at 30 frames per second. (in this 
example 205.86 frames). 

The editor will be capable of sub-frame editing. If the cutter requires that 
all times should fall on frame boundaries, then it should specify it in the 
(still to be defined) cutter abilities request (point 3 below).

I think I could make an educated guess at PropertyPaths, but I'll let you 
explain what you mean by those terms first ;-)

Well, unless I've just added some total stranger, you should now have 
developer access.

Either way, I don't mind so long as you keep me informed as to where it ends 
up!

Cheers,
Jason
