Yesterday I was testing the Multicam feature in Kdenlive, and in general it works pretty well and is useful.

One small feature that would be handy while aligning clips, prior to use the Multicam Tool (especially for those situations where there are no audio cues to sync them to) is the ability to align those clips to markers.

The workflow would be:
1. Review all the clips we want to align, and add a marker in each one, at the desired syncing point.
2. Select those clips in the timeline, RMB click and select Markers > Align to markers".
3. All selected clips are now aligned, so that the marker in each one is at the same time in the timeline.

To decide:
A. How to treat the case of several markers present in those clips. (perhaps use only markers in a specific category/name?)
B. How to treat the case of several "sync" markers present in those clips. (only take into account the first one?)
C. Which selected clip is to be left in place, while aligning. (clip in lower track? first/last selected clip?)

Thanks for listening! :)
