Carl Wilder's writeup from VWR-1825: i really think this issue is worth addressing, with a slight modification that would mitigate for those who are concerned with compatibility. First, I think any change to "double-click" behavior should also have a checkbox in Preferences that switches between the current behavior and any new behaviors. The default(s) can be for current behavior so that existing users are not confused. Second, any argument about consist UI should note that as of viewer 1.23 the pie menus have been considerably reworked, which certanly broke MY muscle-memory and has created a precedent for UI changes such as the one proposed here. Finally, of all the double-click behaviors the one that seems the most "incorrect" today is double-clicking an object. Double-click is a shortcut for a common action, but seriously how often does anyone want to look at object properties? With the proliferation of attachments I would argue that the MOST common use of objects (apart from rezzing, which cant be done with double-click anyway) is "wear". I therefore propose: (a) A new Preferences checkbox that says "Double click object to wear" (b) This preference is OFF by default. (c) When OFF the current (display properties) behavior is active. (d) When ON, double clicking an object will wear the object. As a side note, the WORST that could happen with a spurious double click is that an unusual object ends up being worn for a few seconds (and I've seen that happen enough anyway). Therefore this proposed change has no deleterious effects.
