Maybe someone has already noticed, but there is another inconsistency: The song editor has an "Edit mode", but the piano roll has a "Select mode", both using the same icon. The edit mode in the song editor is the only one that can move a selected block, but its supposed equivalent in the piano roll (select mode) cannot do the same (move a selected block) and one must use the draw mode for this purpose.

I think both the draw and edit/select modes should be able to move a block selected with the edit/select mode in both editors.

So, this is an issue to be taken into account before releasing a new version of the program.
