Back a couple of years I was trying to Maximise my use of the "Lister" and had needs that were not available. About the same time Directory Opus meeting change extending the capability of the Lister.
Here's my problem. I forgot what it was. Actually it involved the "Lister" & "ToolBars". It might have been to load a different toolbar to the current Lister your using, on-the-fly.
I know this is a, crazy request by now that I have a bit of a handle on macros and Opus I feel it's time to redesign my concept of the Lister. Especially since there've been many changes that have been made available to us the last couple of years.
