Please redo the UI of the File/Open page
In Excel, when I use Ctrl-O to open a file, the rightmost column (with previously used files) has its own vertical scrollbar, separate from the scrollbar for the File/Open page itself (I don't typically use Excel maximized). Because the middle column has a huge fixed width, I need to use the page's horizontal scroll to get access to the embedded vertical scoll for the previously used list.
Please redo this UI so that 1) the middle column is resizeable, and/or 2) there is only one vertical scroll bar (the scroll bar for the page). To be clear, for option 2, the page would have to be extended vertically to contain the complete contents of the previously used list (instead of that list being in a separate control with its own vertical scroll).
