It was back in March that Steam first showed off its upcoming redesign for the Steam Library where you can see the list of games you own. The company is now providing some more details about the UI, and how content will be displayed after the change.
The focus of the redesign seems to be on personalising the details page of games with a player's own experience with the game, and also on placing any announcements by the game developer more prominently. Valve says it's aiming for a "richer, more visual layout".
It includes a large hero image at the top of each game's page, with a logo overlaid on top. You can see your play time and achievement completion below the hero banner. Below that are the workshop projects you're subscribed to, alongside a pane to select which friends you might want to play the game with.
The post is aimed at game developers and advises them to start updating their branding assets as the new changes will apply to all titles on the Steam Store, including older titles. Those developers who don't provide curated branding assets will see their games will see a "fallback treatment for the capsule and header treatment" and Valve, therefore, recommends all developers provide personalised assets for their games.
A beta for the new UI is apparently set to go live in just a few weeks, so we'll hopefully be able to test it out for ourselves sooner rather than later.
