It's just the way it works. The Marker pane doesn't show names.
Seems like a strange restriction.
Martin, I've requested this as a feature myself just now. Am commenting here to help illuistrate to Adobe what I need... and also see if anyone has a workflow improvement for me.
I'm hoping to not just have an on-screen easy-to-read list of marker names for a sequence, but also be able to copy/paste the names (and timecodes) in case I need to create a master-list somewhere.
I do need to BOTH be able to hover-and-read in a sequence and also quickly read/search a list.
Thanks for any feature implementation or workflow suggestion.
