reverse all isotope commits:

git revert 517ddd8
git revert --no-commit d284dfe
git revert --no-commit e160c17
git revert --no-commit b4e26eb
git revert --no-commit 0066a52
git revert --no-commit d3b3904

once they are stable we can push them to master. otherwise, they will remain on the isotope branch
