AcidTonic is still having a problem:
Perfect! This is exactly what I wanted. Now I'm glad I asked since I would
have wasted a lot of time hacking around directories.

A few other questions come from your post.

How do i do a STORE.find which will match anything and everything? I tried
using some regex but i kept getting 0 results. *.* would show me the 2nd
level for everything, I just want everything similar to an ls. I found
find_all but it too acts weird and wont show me everything.

Also i wanted to know if there is a similar option to metric.fetch? I want a
way to grab everything. I tried really small/large values hoping to get
everything but it doesnt work. Is there an easy way to get the last X
datapoints? (with a way to get everything I'll just write one if you haven't
already)

This little undocumented api is stunning. Exactly what i was going to
reproduce on my own, now I can get back to my side of the project :)

I am using extjs for my app also, I've wanted to allow my users to craft
their own graphs. Any tips on getting the composer switched to an extjs
fixed sized panel instead of the current window design? I plan to tweak it
and embed it inside my webapp. I'm picking up extjs for this project and
have some basic JSON data grids working, and panels which load fixed sized
graphite graphs.

Of course you'll hear back from me once I'm ready to release any changes I
made to graphite back over for you guys.

Cheers,
Zach
