By "daily" I do hope you mean once a day not once every time you login. The constant reminder that there's a new proposal is annoying enough that it doesn't leave even if I vote or not.
I don't want another popup just for another reminder that I don't need. Of course, this can easily be solved by adding a notification setting in the game to turn off this notification.
Daily would be best, but if it popped up every time the player refreshes, for the 7 day cool-down period, at least it would only be once. Then their account would stay primed for instant unstaking, no more notifications about it.
