So the remote console feature in Spyder 6 seems like a nice idea, but there are some more complex setups that I think could be supported if it was possible to point Spyder to an openssh config file. For example, my IT department make me proxy through an ssh host to get to the VMs where I'd like to connect a remote console.
If I've read the source code correctly, spyder is using asyncssh and that does provide at least partial support for config files by passing a config=.... parameter in connect().
So the request would be to add an optional Config File parameter to the manage remote connections dialog box, to tweak the testing of valid host names to allow profiles in the config file (maybe just don't validate the host if the config file option is given) an then use the config=.... parameter when doing the connection).
(I'd offer a PR myself, but I'm not sure my Python GUI coding is really up to making a usable PR in a sensible time frame!)
