Both Confluence Cloud and Confluence Server have moved search box to top right. You can work around this in Server by putting search above above links. Is this possible in Cloud?
WHY THIS MATTERS:
You have links page open in left margin - if you can't see the link you want - you go to search. In current layout you have to drag the mouse across the screen or move your right hand off the mouse (for righthanders) to the "/" shortcut (why not make is "s" or configurable at least!). Please get UX designers who care about ergonomics and usability, not just about how pretty stuff looks!

PS: As much as Adobe are robbers with the whole cloud model at least they're getting this right - everything configurable, in all/most their suite everything geared towards productivity. Do the same and cultivate your advocates into the cloud age.
