I think this plugin will be broken until:
- reduce queries
- (optional) better design - current is very ugly, slow and impractical.
- remove framework. After all, what's the point of it...
Simple math shows how many more queries makes a new version.
1.9.13 - 37 queries (Home page)
2.0.21 - 216 queries (Home page)
1.9.13 - 10 page loads = 370 queries
2.0.21 - 10 page loads = 2160 queries
Huge difference...even more on the gallery/album page (you can test it).
