Custom reminder messages for personal notes and DMs

Problem

I don't know how you Would fix it, but Fluxer is Very Laggy. Primarily for me, when I'm typing in a server.

Proposal

The option to make your message a reminder and any options relating to it being a reminder could be listed on the right side with the other options. Speaking of specific options, there could be option for when to remind, who to remind(including the person making it. Though in personal notes, it would only have You as an already selected option), and other possible options. I'm also thinking that if someone is making a reminder message for someone else, they could receive a notification to accept or deny it, and maybe user/friend specific settings to auto accept or auto deny reminder requests. As for how it could work, it could notify the selected reminded user(s) when it's set to go off as if it was a sent message. When in the app, it could notify however in-app notifications work. Or have a Reminder Importance Setting for specific reminders(the option as well as other options could pop up for the person set to be reminded, or the reminder/reminded in the reminder set up menu if the same person) that allows the user to change how it notifies while already in app, could be a banner, could bring them right to the reminder message, etc...
