Feature: Modify color of Form Editing Scroll Bar & Allow Pgup/Pgdn to scroll

NeilKY

When editing a form, the scroll bar is VERY difficult to see. The part of the bar that you can drag darkens slightly when you mouseover it, making it slightly more visible but not a lot.

No Mouseover:

With Mouseover:

Also note that you cannot use "PG UP" or "PG DN" to scroll when editing, nor can you use the arrow keys to scroll.

Tldr;

PROBLEM: Combined, these two problems—A) hard to see and B) can't use the keyboard to scroll—make it cumbersome to edit a form with several pages of fields

Feature Request:

1. If the background is dark on a form, please make the scroll bar light.
2. Enable scrolling in forms using the keyboard pgup/pgdn and/or arrow keys.
