+1, me too!
i am a new user (started today, came over from NL/SS).. but thats the first thing that i found i wanted to have that was lacking still when i tried the application out...
- Do not comment on how easy something would be to implement
To the contrary: i guess i know why exactly they were the ones not in there up to now: they are the ones that are either not free or hard to come by (newzbin/invite). => If they were in the list (and switched on by default) a majority of people would be getting errors or at least lose unnecessary performance - or would have to switch them off EACH search request.
=> The only way to solve this would be to have an additional entry in the OPTIONS where every user could (using a list of checkboxes) select his DEFAULT selection of search services.
Dont know if _thats_ whats holding you from implementing it - but PLEASE do it, it would help us NLSS and/or Newzbin users a LOT... currently we are copy/psting a lot between all different search screens - and thats exactly whats NOT the idea of Global search i guess...
