Hi Stef,

Fellow dutchie ;)

I don't think there is an easy way to add this to dolphin.

It "sounds" like you need an entirely different view for that. The stuff
used for the version logic might have some common stuff you'd like to use,
but i still doubt if it would be really useful for your idea.

The best way for you would probably be to just.. make something and get it
working. I would begin by trying to make it work with the version control
stuff, that would be ideal if it suits your needs.
If you have that you can learn from it. See if it works out the way you
hope it would.
You can also discover that the current ways just don't suit your needs so
you need to invent something new.

Hope that helps.

Cheers,
Mark
