following a rider from website

Would be really nice to search for a specific Zwift member and follow them on the website. Now we have to wait until that person is riding and then try to find them in the rider list on the mobile app (not easy at all) and follow them.  Or is there an off-line way to do it somewhere else ?

And maybe have a search feature on the web-site or in the app. So you can search for friends you know are on Zwift.

Would also be helpful to list riders in alphabetical order or have a search field. Somewhat time consuming to scroll to find friends when several hundred users are online.
