Zoom level, too.
I thought this would be a time saver for me. I have a workbook with links to two others. To prevent Excel from locking up, I have to open the linked workbooks first before opening the one with the links. Unfortunately, as tonyw pointed out, some of the settings aren't retained. If I have to spend time resetting my zoom level (on multiple worksheets, mind you), it doesn't result in any greater efficiency. If I had write access to the workbooks I am linking to, I would try changing their zoom level to see if the settings of the first workbook opened are adopted by the subsequent workbooks. This is a great tip, even though it doesn't work in my particular case.
