Our project workspace structure includes 2 sheet templates that can be used to create additional sheets that conform to the column naming convention and column formulas that are used throughout the workspace, thus ensuring consistency in the workspace.
However, these templates are not displayed in the workspace panel view — the folder they sit in is displayed but not the templates themselves. The templates themselves are only visible and usable in the Browse (folder icon) view.
From an end-users perspective it doesn't make sense for the Workspace panel view to hide some of the items in the workspace from the user. Please stop hiding them!
