I've been customizing the style and markup of the galleries that I create with the [mla_gallery] shortcode on my site, and one thing that has begun to bug me a little bit :) is that I have to add my specific style and markup template to each call of the gallery.
It would be handy to have a configuration setting that allows us to define which style/markup template should be the default for the shortcode (perhaps the "default" templates should be renamed to "built-in" to avoid confusion).
That would, for example, allow us to have a "test/experimental" style/markup template to play with, and once it works, simply "switch" to it for all galleries, at once, with a configuration setting (without the requirement to either touch all existing shortcodes, or copy/paste the template text blocks).
I would also like to suggest (if it is possible) to change the appearance/presentation of the templates a bit. Right now, all the templates are listed, which can lead to quite some excessive scrolling and confusion. :) I think a dropdown/selector that only shows ONE template would be more convenient.
Thanks for keeping up the great work!
