Currently each of the Excel add-ins get added to the Home ribbon in Excel. When you have multiple Add-ins installed on a single instance of Excel, this takes up a significant amount of real estate from the default Excel functions.
Any attempts to move the Add-ins to another tab/grouping other than that created during the install results in them disappearing from the ribbon. The only way to resolve the issue is to uninstall the Add-in and delete the custom tab/group created.
Could the Add-ins be modified to either allow for their relocation into custom tabs/groups or install by default into a custom FE NXT tab?
