Implode version 3.0
I don't think I like the new 3.0 implode for one main reason. If you implode 3 staves, you get 3 voices. Select the staff with 3 voices and implode you are left with voice 1 containing the former voices 1 & 2 with voice 3 still there and no way to simply implode it into voice 1.
I was surprised when I used implode and ended up with 2 voices, but I decided that's actually convenient. Knowing that in version 2 you could implode the two voices into one, I tried it in version 3 with satisfactory results.
I think voice 3 hanging out there needs to be fixed and it will be a good tool.
