I think it would be cool if modules could be linked to eachother, with relations such as:
- is a clone of /is cloned by
- is an imitation of/is imitated by
- is an extender for/is extended by
Etc.

Then for example, on the module page of the original Mutable Instruments Plaits, you could show:
- list of all existing clones of the module
- list of any clones that are for sale
- link to a search query in the module finder for modules with a certain relation to the Plaits. You can then further narrow down your search by say height or width.

Edit: I was thinking a bit more about this, we could also consider modules that there is a newer version of a certain module. Then there are also modules that contain functionality from other modules, i.e. the Disting EX does everything the Disting mk4 does, but it is not simply the Disting mk5. The Disting EX can also use MI Braids and Plaits engines but it is not a clone of these either. To consider whether new module versions are an instance of this 'generic' module relation, or a separate attribute type.
