ISSUE
There is a new UI and no discernible way to use the old look and feel of steam on my PC.

OS
Windows 10

STEPS
Open Steam
Take a moment to register the horror and cope with the anguish of seeing this twenty-twenties monstrosity that has been grafted onto this rock of a service
Make tea

RESULTS
Tea acquired, UI is still bad, and change scares me.

EXPECTED
Comedic ♥♥♥♥♥♥♥♥ on forums will help to get some access back to the good old ui, a totally optional step that one can take to opt out of this.
