Implement virtual filters
I used "virtual filters" for lack of a better name, also used by Ge0rG in a previous discussion. In doubt, blame Link Mauve.
The idea would be to have tabs that could "listen" on every incoming

With this I could for example have a tab not bound to a groupchat or chat, and display every highlights I get.
This definitely needs to be defined more thoroughly. Ideas welcome.
