Is there a way to copy (duplicate) a certain ColumnsUI preset layouts?
I don't get the idea... there are "new" "delete" "rename" "reset" buttons... but none for copying a certain columns /panels configuration.
I'd be grateful if someone has an answer to this, because I want to be able to do certain modifications to complex columns presets and every time, I have to start with a blank new one, or else, I have to modify a working preset which I'm happy about.

Thanks

Nobody?
C'mon friends... someone must have faced the same problem at some time...
Preferences--Display--ColumnsUI--Layout Tab--Presets

How can I duplicate (copy) an entire layout?

If you go to the entry immediately below the base of your layout (the topmost entry), right-click and select copy panel, then create a new preset, right-click on the columns playlist entry, select change base and pick the base of your original layout. Finally, right-click the new base and select paste panel and your layout should be replicated.

Can't think of an easier way to do this but hope this helps

Thanks a lot !!!!!!
Thank to you, I found that I wasn't using the latest ColumnsUI, so I hadn't this "copy panel" option.
Now everything's easier.
Thanks a lot again!!!!!
I can't help but wonder why they forgot to implement a copy button on the presets, but anyway... this is the same... it works perfectly!
