If I understand, you're saying the game mod/ api to playful plugins was done by the EroDungeons author? I'll ask them to add that as a feature, then.
The other question: how to force which screen PP is looking at for the overlay? I was trying 1.99.3, and it's always on screen 1 instead of the one where EroDungeons opens by default, which is marked as 'the main display' in windows display settings.
Thanks for your work on this!
