Session recordings are really useful, especially once you open the 'customize properties' and add additional properties that you can then search for. That way it's possible to look for recordings around specific events/interactions.
Things that I would like to see:
use cohorts for filtering. This is currently not possible and is a real limitation
save filters for above 'additional properties' with filters.
It doesn't seem like a huge technical lift to do that. Please implement this to make replays much more useful.
