Well in this case, possibly :-) But my question about context menus was a 
little more all-encompassing. For instance - should the tools be in the 
context menu for easy access, or do they just clutter it up?

That is correct.

This is ok, but there is an issue of which clip gets the marker - should it be 
"all selected clips", or should it be "the clip that you right-clicked on"? 
Which feels "correct" to you?

I think that it is necessary that the context-sensitive version should place 
the marker on the clip at the current seek time, the current "marker" tool I 
have implemented is actually useless because you cannot use it to accurately 
place markers (although I think it might still be useful for deleting them).

You can look at markers in two senses. The first is that the whole idea of 
snap markers is to be able to snap clips to each other. From this point of 
view, we want a representation of them on the timeline.

The other way of looking at it is that you want to be able to place a snap 
marker with complete accuracy. From this point of view, a representation of 
markers within the clip monitor also makes sense.

To be honest, I think that is the answer - there needs to be a representation 
of snap markers in both the clip monitor and on the timeline. There is a 
further extension to this then : when adding markers onto the timeline 
itself, we can again have markers on the timeline, and markers in the 
workspace monitor.

That is possible, the solution via the clip monitor would be to have a button 
saying "add marker". I think that for the moment, I will add this as well as 
the one on the timeline, and see how it feels.

Keep feeding me your thoughts though :-)

Cheers,
Jason
