mBlock5 Category Area Scroll Please


With my 768 Height NotePC, If I add pen and music , Category Block Area refuse to display these icons.

I need to turn display angle 90 to get 1280 height so that pen and music icon visible.

How about adding scroll function on Category Area.

Hoping Good reaction and bug remove

20190729 I realized that Mouse Scroll Wheel Up/Down moves icons in category block.
While mBlock5 Block pallet does not accept scroll. In Scratch3 Block Pallet has tab for scroll.
