A special paint job for donor titles would be good to have.
Problem is, those who award donations tend to overdo it. Take a look at the big Minecraft servers out there. They are literally selling ranks as commodities, They name the price for different levels of ranks, and award people with an unreasonable amount of power. Some of the power include being able to send server-wide announcements, and colorful/blinking chat messages that are more attention-grabbing than server announcements. Oh and I've also seen a server where you could purchase unbans.
Here in TMP we do not want any of those. Period.

A chronic problem that I see here and (afaik) nobody mentioned:
Suggestions are left open for discussion for years and never dealt with. They date back from 2015 and just pile up and expire with the games getting updated. Not a very good sign.
