Feature requests for API browser docs site re giving Feedback and Constructor/Method signatures

1) It would be excellent if each page had a `Feedback` link that would create a prepopulated GitHub issue, just like the main Microsoft docs site pages do.

2) For the Constructor and Methods signatures shown in the various pages, would it be possible to include the parameter names instead of just the data types? Often, just seeing the data types isn't enough to get a sense of what's going on, because you see parameter lists like `(string, SomeClass, string, string, bool, string)` are not very useful to the person browsing the site :)

Thanks!
