Good morning. I see on the plugin page that you are looking for some suggestions. Well.. here we go. ( and sorry for just one post, otherwise it would be a complete mess on the forum )

1. Plugin merge with huntRPG or XP revived ( for blueprint unlocking while still have to collect the scrap and learn them from an item )
2. Quests support ( being able to create quests such as "collected a total of xx wood" or "reaching level xx in woodcutting/mining.. blabla.." )
3. Splitting the "crafting" skill into more related crafting sub-categories like "electrician", "plumbing", "weapon crafting", "ammo crafting" and so on.
4. Increasing resources every xx levels instead of every level with a potentional max.
5. Unlocking chainsaw buff with Woodcutting level 50 or level you provide in settings
6. Unlocking jackhammer buff with Mining level 50 or level you provide in settings
7. A total level in XP (a bit like the system on Runescape ) as a tag in front of the name ( need betterchat for this ) 
8. Option to increase item health by crafting the item in a "tier" system. Unlocking tiers can be done by "tier tokens" and the use of the /tier command* that can be earned with quests or by converting money or RP
9. /tier opens a GUIhud with the tiers to be unlocked, the option to convert and the option to see your profile stats.
