A calendar per resources and A suppliers can be a resources

Dear every body,

First, sorry for my english, it's a little bit so bad.

I just would like to propose 2 evolutions :

1) Created a calendar per each resource or user (like when you create a resource you can choose "is a user"), and each user can be see just his calendar to update holidays or other
2) A supplier can be a resource. Excatly the same as when you create a resource you can choose "is a user", with this evolution you can choose is a supplier and create automaticly a new supplier.

I try acctually to make this evolution, but i'm not a good programmer .

Best regard,

Ben
