I use Qi Tag Cloud on my site. The site is currently Joomla 3.10 but will be updated to Joomla 4, which is not support in Qi Tag Cloud. Tags are used on approx 150 pages, and number into a max of about 350 tags on the largest pages. The tag are presented in the right column, with font size controlled by the number of that tag on the page. Tags are organized by Joomla categories.
Obviously, I want to minimize the effort required to move to something like your extension. If I have to do this manually, it could take a couple of months of steady effort.
I hope that your product is usable on my site, and that you have some suggestions on how to proceed.
