I think polls are a great way to replace the “grant editorial” process in a decentralized way (at least to a certain degree). Basically the step that someone or the community looks at the proposal before the council needs to look into it in detail and decides about it. It’s more or less just an additional filter. I would recommend making this kind of mandatory/good practice for new treasury proposals.
