Huh, I guess I didn't notice this first issue until you mentioned it. Turns
out<http://stackoverflow.com/questions/1552961/ipython-tab-completes-only-some-modules>there's
an easy fix: Run `%rehashx` in ipython to rebuild the database of
known modules.

As for the second issue: We don't automatically import any subpackages
(other than `util`). This was a design decision since automatic imports of
all subpackages would increase load times (there may be other reasons too).
On the other hand, if you just want to see which submodules are available
for import, you can write `import skimage.<tab>` (note the dot before
<tab>) or `from skimage import<tab>` in ipython.

Hope that helps,
