free select tool: Improve moving selection
When creating a selection using the Free Select tool, while drawing using continuous freehand drag (i.e., holding B1 down and dragging), I often stop and reposition my mouse and then restart the selection drag process. Frequently during this restart I accidentally click-hold on the last anchor and start swinging the selection around wildly when my intention was to simply continue adding to it. Moving the selection anchor points is useful, but something I do rarely. I would like a option that would only make the move operation active when I did something like press Alt or Ctrl while then dragging it. This would stop the accidental movement while creating the selection.
Making this optional would allow the current behavior to be preserved for those that like it, while giving others a means to make accidents less likely. One idea would be to include an option on the Free Select Tool Option menu like:
[ ] Hold Alt to Move Anchors
If checked, it would behave as I describe and if unselected, it would preserve the current behavior for those that like it.
