This will be one of the biggest usability improvements to Max since long time if implemented. Please make it possible to scroll in panels even when the mouse cursor is OVER buttons. icons and fields. It will be so much easier to scroll within panels. This is already possible in the Material/Map Browser of Slate Material Editor but sadly it's the only place where that's possible.
At the moment you need to first find safe space where there are no buttons/icons/fields and only after that try to scroll. Sometimes it's so annoying when you want to scroll but you accidentally hit a button/icon/field. It will save so much time on finding safe spaces in the interface for scrolling and won't take away our concentration.
Blender already has this and scrolling in panels is JOY not a PAIN like in Max. Just try it out yourselves and you'll see what I mean. You'll never want to go back to the way you scroll in Max.
