Another small thing that might help with the fact that, when you scrub you get a new region. Hit the backspace key. It will select the immediately previous region you had selected. So undoes the chance in selection made by scrubbing. Not great but a bit of a help.

Pressing Backspace multiple times will recall the last FIVE regions. You can also set the option in preferences to collapse loop regions. With this set, a single click will eliminate the loop region.
