Whoop! Questions (and bugs?)

Hi, just installed the whoop! theme, I like it, great idea. Some questions about:

Bugs
– switcher locator: disappeared. In MultiLocations options are ok (it should show in menu bar) but I don’t see it.
– I changed the css via the whoop! admin option section, but nothing changes, even I disable/clear Gd Booster. The colours (of the header) remain the one of your default demo.
– in General option I selected to show as home page a static page, but after activating Whoop! the home page is a GD home page

Questions
– is it possible to set the header fixed?
– widget “your next review”. How it works? Because I see it suggest to review a listing, but if is a random listing (of more than 10,000) is very hard that users will use it.
– in details page, buttons “Add Review” “Add photo” should remain visible also for not logged users

Thank you in advance
