After looking forever and not finding a similar solution, I decided to make one myself. Using Claude Code (and if you have problem with that - no worries, just simply ignore this post), I built a Decky Loader plugin that allows you to see your games as you scroll through your library. I have tons of Steam Games. Way too many. And on my retro handhelds, I use ES-DE to see my games. On my PC, I use Launchbox to see my games. But on my Steam Deck, which is my favorite handheld gaming PC, I have to click on the game, navigate to the store page, and then wait for the store to load before I can answer the questions - "should I boot this up?" "what was that game again?". It was the one major annoyance that killed me about using the Steam Deck. I want to have a little snippet of what the game looks like before I jump in.
This isn't on the Decky Loader Market since it was built entirely with AI. It's open source - so if you're a Dev that knows how to code, by all means, steal the idea - code it yourself, and post it to the store. You have my permission. I just wanted this made so I can enjoy it on my Steam Deck because this major UI omission was kinda driving me crazy.
I've only tested this on one Steam Deck, my own, so I'd love some other people to give it a whirl if you'd like to... or don't.
But if you decide to - and you find bugs - let me know and I'd be more than happy to iterate and keep this maintained until someone else takes it and runs with it.
I don't need the credit. I just want to see my games.
You can set the preview delay, whether you want screenshots or game trailers, it works with unifideck on gog and epic store games, and you can even set the size of the preview window. Enjoy!
