Do something after user moves a marker

I'd like to update a list of markers [name,frame] everytime the user moves or deletes a marker. Yet, I couldn't find a solution using Handlers, but I have the feeling that it is possible...

The user's actions I'd like to monitor appear in the top info window.

For example :

bpy.ops.marker.move(frames=-1512)

Any hint ? Thanks a lot !

• Waiting for a better solution, I update my list with a handlers.frame_change_post.... 25 times per seconds. That breaks my heart. – Nikos_VSE Aug 28 '14 at 9:29

Currently there are no callbacks in bpy.app.handlers to catch these events. The api we have own isn't well suited to adding callbacks into 100's of operations which would be needed to support customizing the behavior of any tool.
