I love these wordpress plugins for more than one websites. Of course I stacked it. It's an awesome gallery plugin. So far very easy to use and it looks nice.
Awesome that this is on Appsumo...

Improvements:
- please make it possible to change the size of all pictures in the costum grid. Currently if you want to change the thumbnail size of your pictures you have to change it for every single picture. That takes a lot of time if you have big galleries.
