Fixed an issue in the File Explorer that prevented users from navigating to different locations or opening folders.I also improved the Notes app with several new features: users can now import notes from .json or .txt files, undo and redo changes, save notes directly in the File Explorer, pin important notes, search through notes, view version history, and have changes saved automatically in real time.I also added functionality to the sound button, allowing users to adjust the volume percentage, although no sounds are currently available. Notifications have been added as well.
