In the resolve window, the "unresolved conflicts" part, you have buttons on the right "mercurial resolve", "tool resolve", "take local", "take other, "mark as resolved".
I think it would be useful if these buttons were also available as a context menu. This means less moving with the mouse.
ie left-click a file, move mouse to the right and click a button compared to right-click a file, and choose directly from the context menu
This could probably be also useful on the "resolved conflicts" part too
