Problem:

Groups, the Add group button, Web search and the search button for Web search are centrally aligned and it looks odd, because the button "Toggle intersection" and the multiple buttons "Move panel up", "Move panel down" and "Hide panel" skew two of the four more towards the left.

Desired Solution:

Align the text for the four along a common line.

Example:

The text could start somewhere along the red line:

I would refrain from aligning it completely to the left border as there should be a contrast to groups and search fields.
