I have added hyperlinks to more of the technical term appearing (such *[[Spectra]]*). <a href="https://ncatlab.org/nlab/revision/diff/idempotent+monoid+in+a+monoidal+category/2">diff</a>, <a href="https://ncatlab.org/nlab/revision/idempotent+monoid+in+a+monoidal+category/2">v2</a>, <a href="https://ncatlab.org/nlab/show/idempotent+monoid+in+a+monoidal+category">current</a>

   Format: MarkdownItexI agree "idempotent semigroup (object)" seems most suitable when associativity is present. I think "object" can be omitted in this instance, as there ought to be no confusion.

   Format: MarkdownItexIt's reasonable to redirect [[idempotent semigroup]] to this page, even if it's mainly about idempotent monoids. I don't see a problem with terminology like [[semigroupal category]], considering we already have [[magmoidal category]] and the like.
