Add scroll/jump to move Discover time window

[shaunlandau1973]

A common use case for the Discover screen is to move back through time starting from the initially-selected timestamp range. At present one must muck about with the timestamp range widget to achieve this objective.

I much better experience would be to enable the user to scroll somehow. A simple and cheap solution is to add left and right arrow heads to jump 25% in the respective directions, maintaining the duration.

Hi @shaunlandau1973,
Thanks for the idea!

Currently, we have two options to move the time window:

1. Left and Right arrows in Timerange dropdown

2. "Load" buttons on Surrounding documents page

Hope, this helps!
