Search in sys_main_logo

2 Questions:

Where can i find a file with the search bar in sys_main_logo?
I'd like to adjust the margin and style of that particular search bar...

How can i set that the member menu is on the top of the page incept of the bottom?
In 7.0.9 i could adjust that in administration. Now i can't find it.

Hello 

1. Search bar is inserted using Injection (sys_injections table) It calls genSiteSearch method from BxBaseFunctions class (templates/base/scripts/BxBaseFunctions.php file)

2. You may change it via admin panel -> settings -> templates -> settings tab -> 'Default position of member menu' setting.
