Tools for third party developers?

[vectorPhile]

I apologize if this is not the appropriate place to post this. Maybe an admin can move it to a better forum if it's more appropriate somewhere else.

I am wanting to develop some vector drawing tools for my own art, but also maybe potentially for sale or just to give away.
Do you have any resources of places to begin or appropriate ways to start with developing for Affinity Designer?

I program in C++ and several other languages a bit.

There is currently no way to do what you want and you would be advised not to hold your breath while waiting for such functionality.
If you want to ‘add your voice’ to an existing request then, by all means, do so.
