Today I built git annex view, and git annex vadd and a few related
commands. A quick demo:

Not 100% happy with the speed -- the generation of the view branch is close
to optimal, and fast enough (unless the branch has very many matching
files). And vadd can be quite fast if the view has already limited the
total number of files to a smallish amount. But view has to look at every
file's metadata, and this can take a while in a large repository. Needs indexes.
It also needs integration with git annex sync, so the view branches
update when files are added to the master branch, and moving files around
inside a view and committing them does not yet update their metadata.
Today's work was sponsored by Daniel Atlas.
