One of the best features for film is the Find Tempo from Markers feature in Digital Performer.
It would be great to have this sort of functionality. Currently I have to do it in DP and import.

My apologies if there's a script for this but thus far the scripts I've seen do not provide a list of potential tempos based on markers as you'd get from DP.
