Sub Items And More users!

Sub Items And More users!

Hello,
 
I just signed up for the free account but am very excited about using Soho for all my invoicing needs for my company.
 
There are two huge questions remaining before I would be able to move forward.
 
1) How close are you to adding sub items? I have hundreds of products and need to be able to break them down into categories to make adding items to an invoice user friendly.
 
2) Is there the possibility of adding more users? I would like to be able to have 12-16 users.
 
Please let me know.
 
Thanks,
 
Justin
