What I miss from Mercurial world is strip extension:
strip changesets and all their descendants from the repository
I also like syntax sugar of Mercurial for relative revision specifiers where -r -1 means last revision or tip or HEAD. -r -2 its parent and so own. So stripping the last changeset is hg strip -r -1, and the same could be implemented in gitless.
gl strip -1
Of course backup feature is also needed.
