I used to play heavily on a server with the jobs plug in. You gain an income from active jobs for doing things for each job. for woodcutting you get money for each log and different logs get different amounts ect. Each job had abilities unlocked at certain levels. As a builder once you hit max level you could hold right clock and chain 7 blocks in a row in a direction. with digging you could right click and clear a 7x7 square of dirt. Little things like that, They made building and other aspect of the game less tedious.
