• Queued downloads loaded when the application restarts don’t show the transfer bar properly – CatchUpDownloadHistory()
• DownloadHistory “OnNavigatedTo” routine may be using an EpsiodeStruct unsafely
• General concerns that the downloadhistory originally starts off as a structure that linked to the MasterTable. Upon tombstoning etc., the linkage is lost somewhat. Impact? Every time you update the MasterTable episode with progress, you’ll need to reciprocate for the DownloadHistory.
• After tombstoning when the downloadhistory and episode list are no longer linked – do all download manipulation routines take into account that two memory locations need to be updated every time? UpdateBoundTables seems to do this right!
• If downloads are completed when the app isn’t loaded, then there is legacy status text etc. that isn’t cleared.
