I've to test Filr for the needs of my organization and I've got some questions:

1. Is there any way to modify the frontend except of setting a custom picture and background? Customizable templates for the frontend for example?
Just a custom picture and background really doesn't look professional.

2. I need a solution for the viewability of the frontend users. Our customers should'nt be able to see each other. Is there a way to realize that except of putting each user in it's own group?
