I have some ideas which functions you could add. 1. Some sign-related things: colors, edit, ... . 2. Copy & paste for cuboid. 3. Custom stack-size for items (e.g. 32 signs instead of 1). 4. A chunk-regenerator. 5. Item-restore after death (or a DeathChest). 6. Region-protection. 7. Auto-replace for the inventory (e.g. you have 256 stone and build sth., after the stack has been used, the next stack appears instead of the old one). I know there are plugins for all of these functions, but I like 1 plugin instead of 1234.
