If you name your layer "background" it will set it as the page background.

You can manually clear your cache by deleting the folder called "cache" located in your app folder.

Can you create a one page sample for us, zip it up and add it to this site?  Nobody else will have access to it.

We are aware of the issue with deleting pages and it should be resolved in the next release.

Please create a single page sample.  What you are trying to do doesn't sound like "too much".

This should be resolved in the new build coming out this week.

Good suggestions, only challenge is that we are trying to keep the screen real estate pretty clean.   We will definitely consider this suggestion.

An update is imminent (we are hoping by Thursday or Friday).

Just read this so you can ignore my previous comment :).
