Remebering the current position in the (visual) Editor

[VipSaran]

Currently (RIDE v1.3, Windows 32-bit on Windows 7 64-bit) when navigating back to a previous view (by e.g. a back arrow) we are returned to the correct view, but always at the beginning.

It would be usable for Editor to remember the current cell (or cursor position) for the view when leaving it (to e.g. follow a keyword hyperlink) so that when going back we can easily continue where we left off.
