I have a lot of mods that need work but limited time this summer, so I'm letting the community decide what they want me to work on.
BLS2BLB - Converts small saves into bricks, like props. Haven't started it yet, but it's possible to do.
CRP2 - An advanced CityRPG gamemode, my longest developed mod
Pixel Events - A set of events that allows bricks to have dynamic screens and displays
Brick Tessellation - Adding tessellation to special bricks
