Some minor upgrades have also been sent out to the beta channel, such as the option to bypass startup animations by tapping the B button – something we can use when we’re sick of custom 30-second-long launch animations. User-created virtual menu icons, as well as additional controllers such as the Hori Fighting Commander Octa and several third-party PS3/PS4/PS5 controllers, have been added.

There is no news on when these beta features will be included in the main build. If you wish to try them out before the complete release, go to Settings > System > Steam Update Channel and activate the Client beta.
