This may be of use to people who use Steam as their main client but claim a lot of the EGS freebies:
steamsync
The app lets you import your EGS games to Steam as non-Steam games automatically without having to manually use third party apps like
OSOL. It doesn't do the full shebang yet (no metadata import for things like game covers and such) and only works for EGS (would be nice if it supported other clients like Amazon, Battle.net and so on) but I thought it might be useful for those of us who redeem the freebies or if someone caved on an exclusive here and there but still wants to launch their games through Steam.
For people who use Game Pass, there's also
UWPHook, that now also imports SteamGridDB assets so it really is a one-click solution for people to launch their WinStore and Game Pass games through Steam.
I haven't needed an app like this in a long time as I use
Playnite, but with Steam Big Picture's replacement on the horizon I figure some people (myself included) are considering going back to using Steam as their launcher. I hope we see more things like this that fill gaps in the Steam client that Valve refuse to do themselves.
