It seems the center of the table properly conforms to themes, but the outer edge does not. Switching to the horribly-white default theme makes it possible to see as the text is black in that theme rather than white. So it's a temp-fix to get all your transitions set up for now. For the most part use of this is likely set-and-forget for most people.
My understanding is that you would set that common transition as the main obs default one. The trick here would create an UI for that but really easy to implement once an agreement of what/how the use case would beHow possible would it be to have "any" as a destination source? I have a couple scenes where going to and from the scene will have the same custom transition. Currently it's possible to just set the same transition from those scenes to all other scenes, but that can be a hassle when you have 10+ scenes to work with like I have.
Thanks,This is going to be one of those 'essential' plugins once you get the bugs ironed out.
Keep up the good work :)
