I'll try to support you in this effort with what time I can spare. I still use Vessel quite a bit as well, and just haven't been able to devote the time to improving it.
Depending on how we want to go about this, there are plenty of paths we can take and I'm open to the discussion on how best fit your work needs on the project.
Thanks @jesta. It means a lot to receive your support for this as it is your Steem baby. Apart from maybe some review and merging I don't foresee having to involve you too much hopefully!
