as i designed it now, you can go into the settings.ini and create your own profile, and then specify which trackers you want to use that tracker (using the scripts Sidebar), and also configure the search url for each site for that profile (editing each script.ini)... you'll have to do that manually though, since I didnt want to add anything into the main program that would be confusing.. and I figure the more advanced users wouldnt gripe that much about doing something manually =/
but, regarding your question, are you looking for something else?
