For some reasons it would be helpful to see markers set in a multitrack session when editing a clip in waveform. I understand that multitrack markers are linked to the timeline and not to a certain clip in a certain track - that might be the problem. But maybe there is an idea how to transfer the overall multitrack markers when opening any clip in waveform mode.
In Preferences/Multitrack make sure that Synchronize with Waveform View is checked. The cursor will then stay at the same point when you switch between Multitrack and Edit view allowing you to add a Marker at the same place if you wish in the Waveform.
Expanding the marker toolkit, especially the ability to more easily reference markers between Waveform and Multitrack views, is definitely planned for a future release. I'll append your notes to the feature entry in our database.
That´s fine, thank you!
