Current character limit (~512) is really restrictive, especially if you're trying to put, for example, more than one url / slurl in there. (Yes, I know about URL shorteners, they're timebombs; and I know you can attach landmarks. I'm just using these as an example)
We
can
use notecards as an attachment in the notice as a workaround, but that takes up the singular notice attachment slot, which isn't super ideal if you have something that isn't fullperm (and therefore notecard-able) you want to send out too.
New character limit doesn't have to be novel-length; even just doubling it to 1024 would help a ton.
