I like most of what we do today with our sign display which are videos or presentations for meetings in different locations around campus using novisign platform! It works very well when used as intended by its creator but it also could be improved if they took some time fixing minor issues here & there instead focusing so much about user experience improvements (like adding new features).
That would help us improve usability quite fastly without taking too long from launch date till final release version 1st May 2018!! We have been able fix many problems thanks to their support team who answered all questions quickly even after business hours at least once during 2 months.
