I really like ATVFlashB and i know its still a beta. However here are some suggesstions:
Media Player: Since the ATV 2nd Gen. has no internal storage the “Local” source should be removed or at least shown below “Remote” sources.
Menu integration: Instead of having a settings menu in each App these menus should be listed in the native ATV “Settings” menu (new menu entry “ATV Flash” with submenu entries for each app) or in the Maintenance menu. With this done the sources in the Media Player could then be listed directly in the “Media” menu, without the “My Files” submenu.
Bluetooth: Would be great if ATVFlashB would contain a BTStack itself (no need for NitoTV = extra menu entry)!
