I like the addition of the User Techniques and can easily add them to the XML file for the presets. There are two flaws in using them however.
First, when adding a user technique to the score, it tries to add it where the mouse click is to choose it from the pop-up, not on the note you actually wanted to place it. This makes it extremely cumbersome to use. I have to find a place on a staff where the technique will land (i.e. not in between staves) and place the user technique there. Then I have to grab it and move it where I want to place it and to top it off, it disappears while moving it and reappears when I let go.
Second, once you set a user technique, it is set for life. Please add a command to the rules to allow unsetting a user technique much like the "Unset Technique" action. Actually an action to unset all user techniques and a command to unset all techniques would be nice.
