100% agree with your wording of the proposed changes.

Expiration of votes and proxies, based on time.

Notifications on UIs (front ends and in wallets)

& if I may make a suggestion, that the term (time length of vote validity) be 365 days.

That seems to have been a rather amicable figure when mentioned in various witness chats in the past. Although no exact time frame was ever agreed upon by all people in those public live podcasts.

Fully support you putting this out publicly, openly and transparently.
