Topic: nav arrows and thumbnails

Love the work done on SimpleViewer - great scripting!

I have a couple things that I would like to know about customizing.

Can I swap the image nav arrows with an actual image instead of a movieclip?  And have it not treat the image like a movieclip, and just show the image? 
I've done it, but it treats the image like a graphic and applies the color setting to it.

Also, the thumbnails, is there a way to swap the image for the "current selected" instead of the only options of annotating "current: with either the dogear or border?


2 other interests - custom cursors for image nav, can this be implemented somehow?  And any plans to update to AS3?
