Scroll in Color Palettes

I’m working on a font that contains more than 50 colors. Nevertheless it is impossible to scroll to see all the colors, so I would need a giant screen to see them all.

I don’t know if it is because of the number of colors but now I can’t open a file like this. If I try, Glyphs crashes.

Can you send me the file?

And I fixed the scrolling.

A scroll is needed also when selecting the color of the layer. (Thanks for adding the other scroll)
