I have seen very good implementation by codester team on Home Page search with select options of category. But when anyone search any author like type codedaddy no result found but I exist here. If you can add in search option Authors or Users and after selecting and search codedaddy they will find their matched authors then it will be awesome.
Because right now We cannot find authors via their username. We can only search items.
Finding Authors by their name will be good for buyers. Because on the marketplace some authors are doing good but invisible for users.
