Is there an easy way to make a set of buttons that will open the listers I have set up?
I'm thinking of a toolbar that has the existing listers. Goal is to open the toolbar and be able to easily open desired lister.
That's what Lister Layouts are for.
A menu for opening layouts is in the default Settings menu, which automatically lists all saved layouts.
You can also create buttons to open one or more individual layouts using the Prefs LAYOUT="xyz" command.
Or you can create desktop shortcuts to open layouts by dragging them out of the list of layouts in the Preferences window.
