No way to specify gateway url

[sa-]

Description

Hello wonderful people.

I usually start jupyter lab with a gateway url, but I can't seem to do that here :(

Reproduce

1. Open the jupyter lab app
2. Try to enter the gateway url somewhere

Expected behavior

The gateway url is entered somewhere, and I can use my shiny remote kernels.

Maybe this is feedback for jupyter lab and not the app itself, but it would be nice to add/remove kernel gateways from the launcher tab.

One possible solution is to have a server list on the left, similar to what Lens has:

This way one can create new instances of jupyter with different command line args and switch between them.

The photon list component could be used to make this: photonkit.com/components/

Context

• Operating System and version:
• Browser and version:
• JupyterLab version:

Troubleshoot Output

Paste the output from running `jupyter troubleshoot` from the command line here.
You may want to sanitize the paths in the output.

Command Line Output

Paste the output from your command line running `jupyter lab` here, use `--debug` if possible.

Browser Output

Paste the output from your browser Javascript console here, if applicable.

This would be a nice feature, any updates?

I see that there is a command line now, could there be a way to add cmd line args to it?

you can now customize server launch arguments with the newest version 3.6.1-2. please install it and check the user guide for instructions.
