Note that the password protection als encrypts the file.
You can also configure Wieldy to automatically unlock on startup.
Only the icon for locking will remain. I may add a feature to configure this.
Not yet, but an addin could be developed. I'm currently workin on various synchronisation addins. I will release the source code for all addins with the next release.
Autoupdate currently only works with portable versions or when Wieldy is run with user which has administration rights. I did not had the time yet, to download and run the setup.exe file.
