Ban Mouse Drag
mouse drag should be ban'd
Holding down a button and drag mouse is a RSI pain. On trackball, it's also hard. The most natural for drag, is touch screen.
The function of mouse drag, is a cursor starting at pos1 to pos2. It does not require the concept of holding down a mouse button then move mouse. It just so happened that Apple decide to do it that way with mouse since around 1998 and popularized it.
If finger touch screen like phone was created few years before mouse, we may not have a mouse drag today today.
