BlackThorny: Ok then, as we are on the same page, I'll elaborate:
My question was if
Anything that we had on previous Gog shelf and absent while using Fundamentals has any importance whatsoever?
For example - the ability to reMERGE game bundles like they were pre *un-bundling and taking away the manual sort.
* I'm aware the un-bundling was not part of the redesign that took away the manual sort, but it was part of "how it was before".
I think at this point the only thing separating modern GoG + AF from the old style library is the bundled games, but while it would theoretically be possible to bundle them back up... I'm not sure it would be worth the effort to do so. It would probably require a bit of effort to get right (as well as probably checking MaGoG to find which games are unbundled and would need rebundled in the first place)
If there are any other features missing please feel free to request them and I'll see what I can do.
Enjoy the script :)
