Import and split is a feature that I use on a weekly basis. I would like there to be an optional button in the toolbar.
Because… once a week you don’t want to have to pull down a menu for this or use a key command?? 
You could say that about a lot of buttons that are available for the toolbar. I am asking for a button.
Seems like it would be handy to me. Some people like buttons for some things and key cmds for others
