Thanks a lot for your feedback!

You get that when using "git clone --recurse-submodules", but there
is no configuration option yet to switch that on by default (but we
are planning to add one).

Current pull does fetch them (when changes to them are found in the
fetched commits of the superproject), but it does not yet update
them (there is the "recursive update" work in progress to do that).

We do have a command line option ("--recurse-submodules=check" is
what you want here), but no configuration option yet.

Seems like we already solved some of those, and your feedback shows
me that we are moving in the right direction. I keep a list of open
issues we are aware of at:
Feel free to point out missing topics.

Good to hear that! Solving them automatically is hard, only fast
forwards are currently resolved without user intervention.

Right you are, we need tutorials for the most prominent use cases.

That's what we are aiming at :-)
