Horizontal pallete arrangement.

My feature request is an option to put the palletes horizontally across the screen.

Currently you can detach the pallete window and stretch it, however the palletes are still arranged vertically, resulting in empty space being generated and no vertical space saved once you expand the window to the point of one line per pallete.

This would improve screen utilisation when editing scores in "continuous view" mode.

This would probably be really difficult to integrate eh, but thought I'd float the idea if it turns out not to be too complicated.

Apologies if this has been suggested before.
