If a company hasn't bought commercials/project accounting etc.. why have these showing as folders in the main menu structure, would be much cleaner if only showed the ledgers that the company has bought from Sage. Also, would be nice if workspaces were either in the original ledger, or sub ledgered under workspaces, so if the above isn't fixed, it would be easier to remove the workspaces that are irrelevant to the business.
