Another option, maybe even better, could be to apply in QAP same rules than in Win Explorer,
based on user's preferences, (defined in HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\Hidden)
- If hidden files and folders are currently displayed in Win Explorer, display them in LiveFolder's subfolder list
- but if they remain hidden in Win Explorr, do not display them as well in QAP
- and the same about System files (HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\ShowSuperHidden)
Or a mix of my original proposal and this new one....
