This looks like a great tool!
Will it be open source? How easy would it be to integrate it with something other than Trello? (Airtable in my case, but i'm happy to hardcode API access for my purpose)
Thanks!
Right now, I am focusing on Trello, but it's definitely a goal to make things modular enough that users can replace the Trello API with a service of their choosing. When you purchase the asset you will have access, and rights, to modify the source as you see fit, so long as you don't redistribute that code.
Airtable looks really interesting! I'll have to look into it for the future :)
