I would like to make a suggestion.
In this suggestion you can make your own banner. This would be very useful for servers, as people would be able to have their own custom banners. You would be able to use basic pixel art on your banner, so you could make some basic banners. You could choose a basic background colour out of the basic Title colours, as well as your pen colour, with the same basic colours. This Banner would be registered as the banner of a certain palyer or of their build. with the basic 32/64 banner shape image, you could simply edit the banner one pixel at a time. This means that custom Factions and Guilds on servers could have banners, and so that in single player you could put funny banners on enemy buildings.
I hope you people like this suggestion.
