Toolbar on Bottom option needed

[wutech 19]

For users of previous versions who opted to keep toolbar at bottom, v6 toolbar's top-only position (even when collapsed) obscures content.

Add back in Settings > oolbar position so users can choose their own preference.

ALSO.... Since flipping/flicking forward/backward is more natural than down/up, if don't want to forego the continuous scrolling in v6, let users choose their own preference of scrolling horiz vs vertical.
