Filtering by type exists in the current version of the app, but it would be nice to see more robust filtering options (an ability to hide items, filter out rated games, etc.)
Viewing post in Filter library?
*Some* better filtering exists in the desktop app, not the website, but it's still badly insufficient. And that doesn't exist at all on the website, as you see in your screenshot, which is a huge pain when trying to go through all the games in one's library of a certain type, such as "Physical Game", since the app doesn't allow multiple tabs, so you're constantly navigating back and forth between web pages.
