Remove the limits on Excel compatibility.
Before MS bought Visio I used it to track my companies PCs with a Visio Drawing inserted into an Excel spreadsheet. I could link PCs to a line on the Spreadsheet and when I needed to move a PC I could keep the inventory and location in the building up to date easily. Then MS bought it and within a few updates the compatibility between Visio and Excel degraded and I could not longer use Visio and Excel in that way. It remained degraded 'til the day I retired a couple of years ago.
