Enter Dashboard URL text field: pressing Enter is different from pressing the search button

[consideRatio]

What happened:

Pressing Enter compared to pressing the Search icon when having entered a Dask Dashboard URL provides different outcomes.

I've realized that if I hover the Search icon button, it sais "Auto-detect Dashboard URL" which is what has confused me, pressing enter and doing a "auto-detect dashboard URLs" are different, but based on the layout I assumed they were the same: to submit the suggested URL explicitly written out.

My wish

I wish that the UI didn't end up confusing me. I have never been able to have a functional auto-detect button, and that probably makes me even more confused.

Minimal Complete Verifiable Example:

I don't know how to provide this =/

Enter checks the url that you have entered in the box, while the "auto-detect" button tries to find the appropriate URL in your currently active notebook. I suspect what is confusing you is that "Auto-detect" isn't working for your dask-gateway setup, though it's tough for me to tell for sure.

I wish that the UI didn't end up confusing me. I have never been able to have a functional auto-detect button, and that probably makes me even more confused.

I suggest trying a LocalCluster to get a feel for the intended use of the detect button. Getting dask-gateway working with the labextension is tricky, and nobody has really been resourced to work on it, so I'm not sure what the latest is there (see some discussion in #135 and #190).

I Haven't got much to add here besides remarking that this has confused me too in the past for similar reasons as @consideRatio.

I would expect either

• two buttons, one that populates the URL field, another that tries to connect to the cluster
• one button, but with different behaviour according to whether the URL field is empty

IIRC my issues were particularly pronounced when I was using a remote cluster linked via an SSH tunnel,
