Is your feature request related to a problem? Please describe.
Often people want to be informed quickly about a certain topic. Until now, you always had to use the search, possibly with saved searches.

Describe the solution you’d like
It would be much more comfortable if there was a way to automatically assign labels during feed refresh. Possibly with the same syntax that the search already offers now.

Describe alternatives you’ve considered
An alternative would be to display the saved searches in the menu on the left. However, I think it could be resource-intensive to run all searches again and again to display e.g. the number of found items in the menu.
