I've posted a new build for Simple Gallery in the downloads section (members only).

New Features Include:

• In Simple Gallery Latest, you can now use "Caption" as a sort by mode. So now you can display photo's or albums and sort on the caption (rather than just random and latest added).
• Navigating between albums will now not use the # regions by default, this can be turned on in settings -> gallery settings -> advanced settings -> use album anchors
• Added new tokens for the album mode in "Simple Gallery Latest" called [ISSELECTED][/ISSELECTED] and [ISNOTSELECTED][/ISNOTSELECTED], this will allow you to optionally render html based upon an album being selected. 
• You can now use []'s for custom scripts in the album/photo templates for both Simple Gallery and Simple Gallery Latest. They will no longer automatically be removed. 
• In Simple Gallery Latest, you can now move to a FLOW layout (table-less) templates in settings -> gallery settings -> template settings -> Advanded (Flow)

Fixed Bugs Include:

• Fixed an issue with DNN6 and the "manage" button that occurred on some installs. 
• Fixed missing RESX entries in "Simple Gallery Latest"

Thanks again for all your feedback!
