Handling Hashtag Expressions: a AND b; a NOT b;

[iamdtms]

Hashtags works great, I would like to propose multiple hashtag handling option:
Now subscription on a hashtag is okay, but handling connection between hashtags is not.

It would be great to set a rule having multiple hashtags containment:
#tag1, #tag2 aka #gaming #pc

And a a rule where expression NOT contains a hashtag:
#tag3 :not(#tag4) aka #light :not(#dark)

These kind of code structures probably can be found on original mastodon /filters page as well. (see attachment)

That would be a great feature, don't you think? Looking forward to your reply!

Thank you.
