San's hunting log & software tool

This is a continuation of this thread:
http://arkadiaforum.com/threads/sans-hunting-log.12249/

Thought maybe someone here might be interested in a little software tool I made for capturing the difference between two inventory snapshots, so you can easily track your expenses and returns, but also see e.g. which mob drops which loot typically. See the thread above for introduction and download address. It's just a simple HTML page with JavaScript embedded, no installation or trust in some web service required. The tables below can be produced with just a few clicks in under a minute.

As an example, here the results of my first two ARC Faction missions. It is easy to see where there is room for improvement -- too much healing with the Zeladoth, shall look into better adapted armour; gun too small for Whisker Fish, gave up way too much ammo to regen, also took a few hits before figuring out how to tackle them without getting bitten. Ah, and I crashed out and got eaten once, according to Murphy's law that always has to happen the very moment when consequences are most expensive.
