I'm using office 2013. I had input with regards to the xls in 2013.
In File - Open - Recent Workbooks, there's files listed opened recently.
I had hard time to scroll down to list my exact recent file.
Hence I had a suggestion why not a "search box be there" to type the recent file name what I'm exactly looking for to find out instantly instead of scroll?
This might reduce the time of search/scroll and a better option to pull out the file instantly.
