New Steam Deck Plugin Lets You Customise Steam Achievement Pop-ups to Match Xbox, PlayStation, Nintendo

A new Decky plugin called Achievement Customizer lets Steam Deck users customise their Steam achievement pop-ups, whether mimicking PlayStation, Nintendo or Xbox styles or designing their own. As a Decky plugin it should also work on SteamOS-like Linux environments such as Bazzite, and the creator says they could try to make it compatible with the Steam Machine too. It isn't in the Decky store yet, so users must enable Developer Mode and install it from the listed URL, with the code open source on GitHub.
