Hi. I've some suggestions for further updates.
I have a website where about 20 webpages shall have each about 8 galleries = 160 galleries. So it would be very helpful to have a search function and a sort-by-name function in the galleries overview.
All my galleries should have the same Lay Out. So I have to click about 20 Options in 160 galleries each time from the start. It would be a good idea to be able to set an individual set of default options (simply add a button 'save as default'
The width and height parameters cannot be set to auto-height or auto width. That ain't good, as my images vary in the ratio of the dimensions.
It is not possible to change the position of title and description. As my images are small, this means that the text is not near the images.
Nevertheless: Good work, thanks.
