Re: vote process for proposals?

I think it really worth having a voting proposal, as sometime I might lose track of if a proposal is accepted or not and whether it is under development. Beam's process looks promising. You can try to start with that. Another suggestion is it would be awesome if the DL jira queue can have new typ
