[SUGGESTION] Allow customizing activating and deactivating behaviors

[RndUsr123]

I'd like a couple switches to change how the drag feature is activated/deactivated:

• switch 1 (activation):
  A) drag is always activated with 3 concurrent finger events, regardless of timing (current behavior)
  B) drag is only activated if the 3 finger events happen within a specified time frame (150ms maybe?).
• switch 2 (deactivation):
  A) drag is only deactivated after all fingers are lifted (current behavior after v1.1.0)
  B) a single lifted finger causes deactivation (previous behavior)
