Hi Fortis :)
I have some suggestion about tags.
Special Hide tag(s) which is excluded and does not show up in proposed articles.
Example.
I have sponsor article and I tag "sponsor" but I don't want to this article show to proposed articles under article.
But I use this tag to display somewhere on the page in one place all these articles with this tag some slider / module / etc.
What do you think about this feature?

Ps. Add to SEO noindex tags in meta etc. (for all tags)

Regards.

I did as you write.
This solution not working for me because i use external slider who grab article from tags.

I set grab tag article from "hpage" but if someone entered to article suggested article is 98% with tag hpage.
I want to avoid this.

Now we set article in slider manual every single day.

Look :)
First page - Slider (k2 tools, whatever) - > aggregate article tag "XXX"
Article markered tags XXX, YYY, ZZZ

When somebody view article from slider. And drop down sees recommended article. Yes? Yes :) (this is functionality K2). I dont want hide this section recommended article. I want hide/exclude tag XXX because if tagged article XXX , YYY ZZZ recommended is show me only XXX. (I using only 3 max 4 tags)
Your suggestions is unpublished tag in menu. This not working because still tag XXX is is taken with recommendations.

If K2 have options hide (exclude) tags from recommendations article that would not happen. Because would only be recommended with YYY and ZZZ

I know this is now not possible but maybe in feature.
This is my only suggestion.
