Sorry for the delay, been in personal hell recently but have now emerged.
My thoughts on this are based on an older build, installing the latest now, but what I wondered was if it was possible have a system by which we can create a separate logic tree dedicated to dialogue and be ableto trigger segments of this, rather than draw text objects to the screen and hide them for triggering in an event later. The last I tried this, I was making a merchant screen and was drawing text to the screen for every item the merchant sold, manually, and it was rather cumbersome given I'd have to do it for 40+ planets.
Installing the latest C2 build to have a poke and see what else I can do to accomplish what I had in mind, but that is what I was thinking of.
