Make custom palettes based upon advanced workspace default to not enable editing
Custom palettes are TOO easy to edit. If you drag an item and accidentally drop it, the order of items is changed. That usually isn't too big of a deal except for two things. One, I cannot get used to the order the item are in to easily find them when this continually happens. Two, when the items get reordered, it is very difficult to tell the difference between the french clef and standard G clef (when you have bad sight it's also difficult to tell what number is above or below a clef). I have added the wrong clef to many pieces of music and then looked at may last few measures of work and wondered what I did. Of course I eventually figured it out. I realize I can right click the palette to disable editing, but accidental edits should not be so easy. You should have to tell MS that you want to edit a palette rather than edit being the default mode.
