The IDE integrations bit is the most difficult thing for me; there was a fossil plugin for Jetbrains IDEs/IntelliJ, but it stopped being maintained, I maintained it a bit, but a large breaking change meant I didn't have enough time to keep it up, so I had to migrate away. I love fossil, but some things are difficult without a community around it developing the tools for it.

There is a VS Code extension that integrates fossil, and it works almost identically to the git integration, for the most part.
