I think this is a great idea. Good work Mudbill. I'm absolutely going to adopt your specs.
On top of what I mentioned in the other thread, here's another thought: Some mods require the 1.3 beta patch (AMFP assets, rigged Blender meshes), whereas others (The Trapdoor for one) get buggy when the patch is installed.
Here's my suggestion to tackle this: Could the aml.cfg specify which version of ATDD is required? Your launcher could read a compatibility field from the cfg and use it to build a string that is displayed in the description box, for example:
Then it's up to the user to either update or roll back.
(Hope you don't mind me editing your image.) What do you think?
