A thought about a tool in the key editor

I wonder if I’m the only one encountering this minor inconvenience or if there are more people.

If I want to adjust the length of a note (the play length, not the notation length) in the key editor, I can easily accidentally move the note up or down, which is a bit clumsy. If I want to move a note down or up, I use alt + arrow. I can also use the tool in the key editor with the icon of the 2 eighth notes. Would other Doricians also find it more useful if the tool to adjust the beginning and end of a tone couldn’t be used to move a tone up or down?
