Xibo Digital Signage -- Used to managed Digital Signage tvs in the hallways. Gets better with every release. Source: over 1 year ago

/u/slugshead mentioned Xibo. They've discontinued Pi-compatible versions but run on a lot of other things. Player(client) licenses per major version are perpetual, or at least very long. I've seen some weird issues with them, don't know if it's fixed (mostly has to do with display scaling, probably related to the consumer-grade smart TVs I have to run it on).

Thunar a blazingly-fast file manager with image & video previews, as well as plugins. Source: about 2 years ago

I switched to Thunar because of this issue. It has very fast preview image loading, among other benefits. It seems well-integrated into Gnome, even though it is built primarily from the XFCE project. Source: about 2 years ago

Thunar xfce filemanager but works well in other DEs like plasma too. Source: over 2 years ago

Not sure how i3wm can help you with that. It would have to be implemented in Thunar itself. I would check Thunar's documentation first. Source: over 2 years ago
