The simplified signatures would be show for the main signatures, i.e. the ones with a light blue background, and the full signatures would be added at the end of the documentation for each symbol.
I like it. Some of my code also features a lot of free functions with template constraints and it does get a bit much.
Related remark on the other side of things (more text!): documentation is currently lacking UDA annotations [1] and I would love it if that were to be added at some point.
