Could you make this description a bit more professional and reminiscent of the extension's qualities?

On scroll is available in native scratch when doing:

when [up/down arrow] pressed
if <not <up/down arrow pressed>> ?:
    scroll action
endif

Because the hat block detects scrolling but the key boolean doesn't, so you can detect scrolling like this.

I realize this, but I thought this would make it easier, especialy when using the other scroll block. also it works with both at the say time.

That's a valid point, but it's still probably not worth adding a whole new extension to the gallery though
