Not sure if their is a proper place for this, but I have a feature request that I think would make sense for any site using this. When setting up a filter to be displayed on the main page you should have an option to also choose which ones show up for the All Categories selection. If a listing field is really specific to a category and you want to use it when that category is selected, but it doesn’t make sense to have it displayed on the all categories selection.
Thanks for the feature request! I totally agree, something like this makes a lot of sense. I don’t know if/when we’re going to build this but I do agree that it’s a good idea.
