I will check, how I can re-add some sort of locking functionality in the next version. Maybe just one button for toggling between locked and unlocked.
Notes are automatically created, without confirmation. I don't see a need for a confirmation dialog. Each new note is just an empty file in /home/user/.yellownotes It doesn't take any space on Flash/SD card and creating a new note doesn't take any longer than switching to an existing one. It's like all 99 note are already existing and you just have to put text into them.
The new version is still doing this. I have to check how this is currently being done. At least there seems to be no code in the yellownotes applet, which is causing this behaviour. So I guess it's something which is automagically done by the application framework. But I think such a functionality would make sense. Or once I have again added an lock/unlock button something like (configurable) transparency when the applet is in view mode and no transparency when it's in edit mode.
