They say they're working on it in their most recent dev log
No, my problem is the client itself. The only way that currently exists to work around the problem would prevent me from uninstalling games, managing downloads, and accessing most information about the content I'm supposed to own. And even doing that, there's a high risk of a simple misclick causing a migraine which has a risk of putting me in hospital because of how severe I get them. None of which is an acceptable workaround, particularly not 18 months after Valve was first made aware of the problem. There WAS a better workaround to begin with but it was a third-party option not supported by Valve and they've since blocked access to it.
