Neat!

I know very little about licenses. This on is GPL4. Would this license support business use or even forks a hacker may want to create to play with?

In terms of License, it is actually LGPL-3.0 License, the same as Qt itself and some of the dependencies it uses.

This means that you can develop proprietary (closed source) plugins to create your own custom interfaces to parse data, if you want/need to.
