Ease of use for custom parts

As a new user I seem to love Fritzing, however I would like very much to use custom parts. And even adjust the measurement of the breadboard in my sketch.

Tried to find pout how to do so, but … OH MY!
That is a very, very long way to go with a lot of actions to be taken in InkScape or AI.

I really wish it would be more user friendly: copy, paste and edit in the Fritzing app itself.

Am I alone in this desire?
Anybody any thoughts on this?
Anyone already working on it? :face_with_spiral_eyes:
