TLDR
Proposal editing: allowing proposers to update their proposal’s transactions and text description, during the Updatable period only, which is the state upon proposal creation. Editing also works with signatures, assuming the proposer is able to accumulate signatures from the same signers.
Propose by signature: allowing Nouners and delegates to pool their voting power towards submitting a proposal, by submitting their signature, instead of the current approach where sponsors must delegate their votes to help a proposer achieve threshold.
Objection-only Period: a conditional voting period that gets activated upon a last-minute proposal swing from defeated to successful, affording against voters more reaction time.
Votes Snapshot After Voting Delay: moving votes snapshot up, to provide Nouners with reaction time per proposal, to get their votes ready (e.g. some might want to move their delegations around).
Proposal editing
Proposals get voter feedback almost entirely only once they are on-chain. At the same time, proposers are reluctant to cancel and resubmit their proposals for multiple reasons, e.g. prefering to avoid restarting the proposal lifecycle and thus delay funding.
