Here are three plugins that I have used before that I would love to see added here! They are all quite simple and lightweight!
1. Armour Hider (http://dev.bukkit.org/bukkit-plugins/armorhider/) (http://dev.bukkit.org/bukkit-p…es/10-armor-hider-v1-2-2/)
This plugin allows you to wear armor, but make the armor invisible! I like it because we all spend a lot of time making our custom skins, just to cover them up with ugly armor. This lets you still get the protection of armor without the ugly look.
2. Craftable Horse Items (http://dev.bukkit.org/bukkit-plugins/craftablehorseitems/) (http://dev.bukkit.org/bukkit-p…aftable-horse-items-v3-0/)
All this does is add craft recipes for horse armor, nametags, and saddles. These items are extremely rare and hard to find, and when you have a couple people playing on the same server, there really aren't enough to go around. This fixes that!
3. AutoPrice (http://dev.bukkit.org/bukkit-plugins/autoprice/) (http://dev.bukkit.org/bukkit-p…auto-price-version-4-035/)
This is a server shop that works with a GUI accessed from anywhere via a command. It automatically adjusts prices of items bought and sold based on supply and demand of the items.
