Not only does this plugin not allow many simple areas to be customised in the app like font sixes for responsive, the features it offer are very badly implemented.
Want to filter your posts using a filter option, sure go for it, but if you only wnat to show 10 on the page (as showing more has serious memory leaks and will break your site loading more than 20).
Then the only filters this plugin will illogically pick up are for posts shown on each page (so if you show ten and have 40 so 4 more pages to see other grid posts, the filter will never show what is from any of teh other 3 pages) crazy!
So no one will see any other category options etc in the filter meaning it is basically useless.
Oh yes and the filter drop down will not work on mobile as it will pick whatever you touch as you start to scroll and then you have to mess about resetting that to get it back.
And the best part is the provider here will never help you and just say this is not a dedicated plugin for that, thanks.
And will not answer any of your other actual issues with basic performance and features of a paid-for plugin.
All in all VERY poor, I am using it as I need a non ajax feature but wish they could be bothered to help people with clear needs and make this a good plugin.
