The latest release of the free Tag Groups and the Tag Groups Premium WordPress plugins bring you a minor bug fix and several enhancements.
I updated several Gutenberg blocks to offer more options that are available in the corresponding shortcode. The Shuffle Box understands now the parameters tags_post_id and groups_post_id that you know from other shortcodes.
The new Dynamic Post Filter With Toggles opens now all accordion panels where a filter is active when you return from a post (using the option persistent_filter).
It also received a new parameter: default_show_posts. If you activate it (default_show_posts=1), the post box shows an unfiltered list of posts when no tags are selected. Otherwise it would present an empty list.
