Hi goliard,
A completely new version, SEEVN 3, is being created to fill those gaps and include new features. It's a long process since the project is built from the ground with latest technologies.
Sorry for the almost non-existent support, but providing it realtime is too expensive for an indie operation like this. The little funding and time is best invested into effective development and finding ways to keep it as free as possible.
It's better losing a lot of users now but then getting to a solid product that will have a way larger user base that enjoy it.
Glad to see you around, check again in a few months.
