Advanced Search more lines

Hi
Would it be possible to add some extra rows in the advanced search (currently 4 are available). I like to use this to save different queries and for some of my Ideas, I would need more rows. Also, it would be cool if the "and/or" option was available for each row together with the option to add a bracket to do something like this:

(Condition1 or Condition2) and Condition3

Also, it seems that while the query will save the settings available in "search" it will not save the setting in "setting" tab. (For example, this "or/and" option)
