Roku App & Recording Conflicts

My wife was watching a movie (on regular TV, not on Tablo), and found she had to run an errand - so I suggested recording the rest of the movie on Tablo.  So in the Roku App we found the movie and selected the record/schedule option - all set.

When we got back I was surprised to find out that the movie did not record.  When I investigated I found that my 2-tuner Tablo was already recording 2 other programs at the time.  So my Tablo didn’t have a tuner available to record anything more.

@TabloSupport - suggest that the Tablo Roku app make the user aware of recording conflicts, like a warning message on the screen where the record option is, or just prevent me from clicking the record option in the first place.
