More Options for UI Vertical Scroller
- Option to stop scrolling momentum when scrolling past first / last item (still draggable in that direction) - Explicit function to recognize / set array elements in case they were changed - Resize elements to match elementSize rect object (defaults to center object), scaled using modifiable elementShrinkage and minSize - Detect focusedElement and trigger event if focus changes - Option whether to make unfocused elements interactible or notpull/413/head
