No classes have changed with the frontend css only some options.
You should always upgrade plugins on a local version first to see if there any issues with your set up or complete a full back up as advised through out WordPress documentation.
Any unpaid work that you do is entirely your decision, the plugin after all is free in itself so you could always code your own version and no future upgrades would effect your custom set up.
As per the bad review you have left, if you had taken a backup of your site before upgrading as instructed in all WordPress documentation then the problems you are facing would be an issue as you would be able to revert back.
Secondly you can revert back to old versions by clicking on the developers link/tab in the plugin page and downloading one of the 2.x versions.
Dont get me completely wrong, i appreciate all work people put in making plugins, and yes I should always have a backup of everything I use.
Still would be handy if there was a preview for the upgrades available somehow, this did break my sites functionality for a while.
btw. is there no way to add an alphabetical ordering, they only appear in the list in the order the posts are posted.
It has been added to the feature request list but there is no particular timeline for new features to be added at this date.
btw, are there only 6 filter categories possible? every time I try to add one more it just replaces another which it removes so I can not get all categories to show.
I just noticed that myself too, this is not a limitation but a bug. A fix will be provided tomorrow for it.
Unfortunately had to remove the plugin since the customer needed an alphabetical list due to the fact that there will be 3000+ items filed and this would become unusable without sorting.
I do hope you continue with this plugin, it has all the possibilities to become fantastic.
P.H.
