I'd like to "Open All" on double-click.

Such an arrangement could lead to confusion, in my humble opinion.
It would seem that you use this function a lot ?

Nice idea. Ideally flashdial (or any program) should state all of it's possible commands and you are free to configure how to activate those commands.

Really... do you not think this would cause unnecessary complication and confusion.
BTW, the program in question is called Fast Dial.

Many thanks

I don't think so. Clicking once on a thumbnail opens a folder and clicking twice on title bar opens them all. No confusion (for me).

Fine.
I often double click on a Folder cell in the hope of opening it.

It would seem that you use this function a lot ?
Yes, I do.

Anyway, I did it. It's not configurable through add-on preferences, but it does what I want.
In file fastdial.tpl, line 44:
].openAll();">

Well done !
I am glad this works fine for you.
