Make them usefull at all levels and remove the restrictions on houses. if i want all 8 in my small or medium house let me do it..

I dont think any buffs they added would need timers though. They could simply just require proximity to the workbench. or alternatively actually craft on the work bench. this would require some animation work to be done but would be cool i think.

I'd like to see them just add a tiny amount of stats, not that they're needed with how much melding you can do but still be nice to see soemthing thats actually useefull for crafters of all levels.
