Where would one find that?

Same. The dev is very active and open to suggestions. I’ve been using it for a couple of months now and it’s working great.

KeepassXC is great, but I realised very late in the process of setting it up, that the browser extension does not support Flatpak based browsers: “Please note that in general Flatpak and Snap based browsers are not supported, Ubuntu’s Firefox Snap being an exception.” (https://github.com/keepassxreboot/keepassxc-browser/wiki/Troubleshooting-guide)

I hope this might change at some point.

You have to read further. To quote some of it:

“You use steam-installer from Ubuntu repos. There is also the official .deb installer from Valve Their differences: a) Valve’s Steam & steam dependencies get updates. Ubuntu package does not. For now in Mint 22 this is not a problem. Both packages are in the same version or they were the last time I checked but this was quite recently. b) Ubuntu package still uses an obsolete folder layout in your “home” that official Steam doesn’t follow any longer. It was creating some problems.”

This is an older thread but as I said, it was just an example. There’s tons more on that forum.

In Mint most people recommend installing Steam directly from the website as .deb. There are dozens of informative threads on the official forums, which also explain some differences of the installation method, for example: https://forums.linuxmint.com/viewtopic.php?t=427582
