just a short update:
I work on pycrawl_itemdemo but it is not done yet. While the demo is working in parts ( you can correctly inspect stashes of many items, you can pick up items etc. ) i keep rewriting it over and over because i have not yet found a good architecture for all my classes. Partly, because i'm never sure what kind of features i actually want to have in the itemdemo. Hopefully, you will see a working itemdemo soon.
No separate Flattr-Button this time.
