+# TODO: * implement git-p4 rollback <perforce change number> for debugging
+# to roll back all p4 remote branches to a commit older or equal to
+# the specified change.
+# * for git-p4 submit --direct it would be nice to still create a
+# git commit without updating HEAD before submitting to perforce.
+# With the commit sha1 printed (or recoded in a .git/foo file?)
+# it's possible to recover if anything goes wrong instead of potentially
+# loosing a change entirely because it was never comitted to git and
+# the p4 submit failed (or resulted in lots of conflicts, etc.)
+# * Consider making --with-origin the default, assuming that the git
+# protocol is always more efficient. (needs manual testing first :)
