x/tools/cmd/godoc: Possible improvements #5637
Description
Some improvement we could make to godoc. Split these up into separate issues if it's easier. * Add the ability for godoc-specific comments. This would not be markup as such, but would be ways to organize the presented docs. For example, a way to indicate which names in a package are important and which are not. The important names would appear first. The unimportant ones would be hidden by default. * When the text has a capitalized word that is the same as an exported name in the package, link the text to the docs for that name. * Provide some way to automatically know which types implement which interfaces, ideally across packages.
