I'm planning on releasing a new wallet to replace Vessel with. In the short term, yeah I'll make sure Vessel is still working, but long term it'll eventually it'll be discontinued too.
One of the things I'd like to do is make an easy export from Vessel and into this new wallet process. Try to make the upgrade easy.
Why not join forces with me and make a gui front end for steemboat. I will put it up on github. It uses python so it runs on 32 or 64 bit. It should work on Windows too!
