is it possible to show the complete search field in the title bar (without editing css)?
In the free version, the magnifier is positioned in the header and overlays in special cases ans screen resolutions graphics and text.
Is there more configuration flexibility in the forthcoming Ultimate Pro-version?
Sorry for the late reply. We are busy on Ultimate Pro.
Back to your question you can hide the search from the header via theme options because of the theme design and layout it is not possible to show complete search field in header. You can try using search field in sidebars there you can have a complete search fields.
