Visibility based on tags

I’m not currently a user but Your description asked for suggestions.
How about visibility based on user tags. Eg. If a user has a crm tag showing they have completed activity X then show content Y, otherwise show content Z.
With a series of these sections you could build up the content of a page completely targeted to the particular interest/ needs of the individual user.

Not an appropriate approach for most pages, but could be a really useful approach for some pages. Eg I have an e-learning site where I’d like to give some activity recommendations for my users, but the appropriate activity changes according to the date of their exam and the lessons they have completed.
I can apply tags using wp fusion or groundhogg but I’d like something like your plugin to adjust page content.
