I’ve seen your video on the taxonomy list block. In the video, the exclude option (source: current) offered the possibility to exclude a taxonomy (categories, tags etc.) completely. Currently it seems that you can only exclude individual categories or tags.
Some more thoughts on the taxonomy list Block
These are not bugs but some things I came across playing around with the taxomomy list block:
In a template, it’s only possible to insert blocks into the taxonomy list block if a dynamic preview other than current item is selected. Maybe preselect newest post as dynamic preview when template editor is opened.
It would be great if there would be the possibility to exclude the current item, for example to display all categories but the current one on an category/tag archive page.
For beginners it’s quite hard to understand how the block works. Maybe add a short description that you need to add a text block and select the dynamic source “taxonomy query”.
Keep up the great work!
