Arpeggios and Glissandi missing from "Pallettes".
Using Windows 10. I write slide-guitar music. Use glissandi a lot. Moved up from Musescore 2 to Musescore 3 but found Arpeggios and Glissandi not listed on pallettes - only on Master pallette. Any way to move items onto "Pallettes" from "Master Pallette"?
