@brokensmile: Try running
If it says that there is a new version of AppLock available, then it is ready. Until then I am working on it.

@Everyone else:
Status update, I am busy trying to fix a bug in the daemon that causes it to crash when I add a DBus monitor from the UI. This may/may not be a limitation of libdbus and I will look into it. If it is a problem with libdbus then I will have to restart the daemon after each set of locks is added. That shouldn't be a major problem since I will just add a "Save" or "Restart Daemon" button to the UI. It just results in a slightly longer period between clicking save and having the changes take effect.

I am also working on displaying the current lock status of an application as an icon in the list to make it easier for you to view the currently locked items, I may also add a set of filters.

The UI has also been modified a bit, it now shows icons for the applications in the list as well as in the details view and it has been turned into a fullscreen application (supposedly that improves the performance of QML apps).
