@colinsky : the Trinity "dictionary" is based on EDICT. ENAMDICT is not included. The search in Trinity is very unforgiving, there is no wildcards for example. So in doubt I recommend to enter the word as hiragana, or try a different word ending (adjective, verbs), and 95% of the time you should be able to match something.

The development of Trinity "alpha" is frozen. I have been rethinking the flow of the application many months ago. The alpha version is nice to use in a traditional edit falshcard / review flashcard way, but it doesn't really implement the concepts I had in the first place. The new workflow is also mcuh better suited for making a succesfull stand alone site (hopefully).
The "alpha" version is still active on this site, because there's a few regular users who've entered lots of data, and it doesn't really cause me any trouble to let the app run. The new app has a different workflow, but the basic functionality is very similar, so the current user's data will be ported over.
I really have no idea when I will start working on the new version. I just know I haven't given up on it yet. Right now I'm busy rewriting the old site's code, something hopefully I will never have to do again. Not really hard, just a big waste of time because this site was my first php project and web app. When this site runs on a proper framework (hopefully within next month), is when I'll start looking at Trinity again.
That said, if you find a nasty bug somewhere, I try to fix it asap.
