Adding more support to this issue. While Orion seems to remember the URL "server.home.lan/" after an initial entry of "http://server.home.lan/", I expect it to resolve "newServer.home.lan/" on the first try, without manual typing of the protocol.
This behavior is making it challenging for me to use Orion out of the gate. As a general rule, I want my browser to respect my local dns search domains in some way -- let me configure the browser to recognize those domains and try both https, http, and no search, or give me an ending character (e.g., the trailing slash, or a trailing period) that will tell the browser to try both https, http, and no search.
