We have some sheets that draw in data from other sheets (Inbound links) and deliver data to other sheets (Outbound links). However, the Manage References menu (right click on a cell) only shows Outbound links. Also, you cannot stretch the Sheet Reference Manager dialog box to see all details.
This is particularly problematic if you create a new workspace using Save as New because the sheet in the new workspace will contain inbound cell links from an OLD workspace. Very dangerous.
