OK, you want an integrated tool. Integrated tools are great: I have a nice, handy multitool on my belt. It's the tool I use most.

Impossible. A multitool cannot do all of the things a well-stocked workshop can. The architectures are different.

Your program will probably never export designs to other layout programs. It will never support a variety of simulators. It will never support symbolic circuit analysis. It will never support scripted documentation generation. Or the other things in the open-ended list a toolkit can support. 

That's fine for an integrated tool: target the specific flow you want. It's no doubt what the majority of users would prefer, at least at the start, and gEDA will still be around for those who need more.

I cheer for your success. Both approaches are needed.
