Reduce the wasted space above the spreadsheet!
Reduce the wasted space in the spreadsheet. Referring to the ribbons and spaces above the actual spreadsheet. Especially when viewing multiple files in horizontal arrangement, where there are groupings, the actual viewable spreadsheet real estate is tiny. Very annoying and unproductive having to constant scroll up/down the multiple files. In the past, it was possible to lessen the wasted space but somehow with the new ribbon design, you forgot why people use spreadsheets in the first place, which is to look at data not view the scenary.
You can minimize the ribbon to a single line by double-clicking on the active ribbon tab, or by clicking the ^ in the bottom right of the ribbon. That will give you more vertical space for your content.
