Hi Gumbanomicon,
it seems that my answer came out a bit to rude last time. First of all, I wanted to say thank you for all your questions and feedback. It helps me tremendously when working on the plugin.
Regarding my last message, I just wanted to say that from my standpoint the feature of multiple node unlocks doesn't outweight the amount of work that needs to be put in.
It's actually quite hard to make this plugin work in all use cases. Most games might actually prefer more icon based skill trees like League of Legends Masteries, Shadow of War or Assasins Creed skilltrees. So it might be worth moving the plugin more in this direction. I'm definitely look into such visual options, but at the moment I can't confirm anything.
Best regards,
Felski
