Neptune 15.1.0

* Option to set the minimum box width for the expander. This is helpful if you have long captions on portrait-mode images or videos.
* Updated version of the Floatbox script.

* Option to open PDF's in a new browser window/tab, rather than in an expander. This is not the default, but is the safer choice. Please read the "Browser support" section of the user's manual.
* Simplified navigation on PDF pages.
* Updated version of the Floatbox script. The previously encountered caption problems have been fixed, and this version contains some fixes for some odd PDF problems.

* There have been several bugs in the Floatbox 8.2.x scripts that cause various problems with captions. I've reverted to Floatbox 8.1.3, which wasn't similarly afflicted.

* Option to use fixed-shape thumbnails. If you select this option, you can also specify the content of thumbnail tooltips and control more of the font characteristics of thumbnail captions (link decoration and text shadow).

If you are modifying an existing Neptune project, and change to fixed-shape thumbnails, the thumbnail image bounds should be checked before making an album.

For justified thumbnails, high aspect ratios work best, like 1000x250. But for fixed-shape thumbnails, more normal thumbnail image bounds should be chosen, like 300x200 or 180x180.

* Option, when not using fixed-shape thumbnails, to constrain the aspect ratio (width divided by height) of the thumbnails, with a minimum of 0.5 and a maximum of 2.5. This prevents panoramic images and exceptionally tall, skinny images from producing thumbnails with extreme aspect ratios, which tend to distort the thumbnail table layout.
* Completely revised method for handling folders and PDF's that don't have a representing thumbnail image. This includes the ability, when using the Custom style, to specify the background color behind the generic folder or PDF icon; preset styles use a color-matched background.
* Improved handling of thumbnail images that are smaller than the user settings require.
* Option to include a count of the images in each folder.
* Option not to hide the image counter on mobile devices (to save space, hiding the counter was the default in earlier versions).
* Unsupported objects (for example, Word documents or Excel spreadsheets) are now automatically excluded from the project.
* More selective copying and loading of resource files.
* More selective CSS inclusion.
* More efficient folder thumbnail sizing.
* New PDF icon.
* Shortened transition time from video and PDF poster image to content.
* Album generation is aborted if you choose non-fixed-shape thumbnails, but also choose thumbnail image bounds that have an aspect ratio (width/height) that is less than 1.0. The justified gallery of thumbnails is fundamentally incompatible with portrait mode image bounds.
* Updated version of the Floatbox script.
* Default for video autoplay set to false.
