WebPlanner: inconsistent icons for hide-reveal panels

There is a minor inconsistency with the interpretation of the two buttons for hiding/ revealing the left & bottom panels.

Left panel:

• click < to hide
• click > to reveal

Bottom panel:

• click ^ to hide
• click \/ to reveal

I think the 2 left panel symbols better reflects the intention, and similar to other web apps; the 2 bottom panel symbols are counterintuitive. But agree or disagree, one set of symbols are inconsistent.
