Great plugin - keep up the awesome work.
I'm wondering if it's possible to update the plugin to add an ID to the filter options (perhaps the category name) so that from the URL it's possible to send a link someone so that it changes which filter starts as active.
So if I have these as the filters showing:
All, Category A, Category B, Category C
I could send someone a url like https://site.com/pagewithpostgrid/#CategoryB
And even though I have All as the default in the settings, the URL would force the Category B to show.
There would need to be a way to have the spaces in the category name removed.
