The Chinese were most dissatisfied with the way Microsoft Office handles access to multiple open files. Enter OfficeTab. You’ll need to hunt around on the page to find the download link. But once you do, download and install are a snap—and the app functions as advertised.
I’m currently using Excel for project management—one spreadsheet per project —plus a single spreadsheet to keep watch over the project portfolio and capture metrics. Linking from the dashboard workbook to an individual project workbook (a la Firefox!) is a pure joy.
谢谢你!(And thanks to BNET for the heads-up.)
