In addition to dragging the Context Blocks section of the logic designer of UI-Builder to see more context blocks, It would be great if you could also scroll the Context Blocks section of the logic designer of UI-Builder by mouse-over and using the SHIFT/MouseScrollWheel to scroll them Left/Right as well.
It would also be great if you could get a tooltip of the name of the property block when you mouse-over it, in case the set zoom makes it too small to read.
