GUI filters vs advanced search

[aisbergde]

We have GUI filters and we have advanced search. But it looks like, we miss some integration between.
It would be fine to define GUI filters and to save and restore them. There have been some issues, but they are closed because of the implementation of advanced search. These issues could also be reopened.

Some ideas:

• convert GUI filter settings into advanced search syntax and allow saving them like search queries
• reverse conversion from advanced queries to GUI filters will be complicated or impossible. But maybe it could be possible in some cases. Maybe queries created from GUI filters could be flagged and therefore a reverse conversion could be possible.
• save and restore GUI filter sets independently of advanced search (this would be very user-friendly, because no search syntax is required)
