This relates to channels and the option to advertise torrents therein.
I really love that feature, especially the options to "mirror" by status or category, i.e.
##mirror:standby&offline
##mirror:seeding
##mirror:downloading

I would ask that an override be added to this functionality, where:
individual torrents or groups/categories of torrents could be tagged "private" or "topsecret" etc and that would override ##mirror:seeding for example.

This could be by using the category field or a special "KeepPrivate" flag.

If a user creates a "Private" category, when going to //[+Add]/, these would show up on the  column. As is, the only option offered is to

And such a "do not advertise" flag must override all other entries, such as mirror:seeding or mirror:downloading with something like:
##hide:private

The user could keeping seeding/downloading these torrents, but would not be advertising that fact in the channel shares list.

Instead of just status changes, be aware you don't NEED to say whether the links in your SHARE are a status.
You can also share categories, just select the correct under "ADD" -> mirror

Also with recent changes to ##mirror behaviour, you should be able to keep any number of mirrors in the SHARE list.
(Thank you for global SHARE, it is very useful for tips and a "catch all")

N.B. re: original feature request, not sure you really want to have another level of abstraction in the background with Tixati having to check your "NOSHARE" whenever a share window pops up.
If you want private transfers put them in a category. Don't apply status willy-nilly. Make sure you know your ##mirror parameters. Make sure you don't label your SHARE categories...
