Here’s what I found.

Why does Totem need to be replaced?

Totem is still a GTK3 app and is unmaintained (in part due to a crusty codebase), seeing no major development in years. Replacing it with a modern GTK4/libadwaita app designed to use modern technologies and meet modern needs has been a “high priority” for GNOME.

I do wish it had a self hosted docker though. I could see Proton mail and thunder mail adopting it that way, which would be neat.

Gitlab Id say. It even works as a OAuth server. The docker container is very easy to setup.

Be sure to not reproduce.

I have a birth bath I don’t ever replace the water in. Its like a shrub to me.

I do Ghostfolio for my stocks. Though I paid for it to support development, its quite cheap.

Well I mean for corporate use. Everything you use will be through a web browser and all the data will be stored on corporate servers.

It will all be Chromebooks and software as a service by then. Unless you work as a SaaS vendor, then it will be automatically orchestrating docker containers.
