For handy reference. I hope I got all permutations here.
Two things I didn't manage to figure out:
This toctree thing:
checking consistency... /home/boud/dev/docs-krita-org/user_manual/autosave.rst: WARNING: document isn't included in any toctree
And how to refer to saving for the web:
/home/boud/dev/docs-krita-org/user_manual/autosave.rst:31: WARNING: undefined label: saving-for-the-web (if the link has no caption the label must precede a section header)
