I like the idea of Pijul, and checked it out a couple of years ago. Some basic quality of life features were missing, and are still missing.

For example, diffs can't show context. They show lines removed and added, but can't show the previous and following line because of implementation details.

Here's a diff: https://nest.pijul.com/pijul/pijul/changes/OMGL7JBCLSHWTIYP7...

It's a little thing, but when looking at a diff, seeing three lines of context helps enormously.
