I have installed it, but only used it to look up "quethe".
I don't use a dictionary very often, but if I do, it's usually to look up obscure words. So, I think your wiktionary will be very useful for that when those times come up.
May I ask, what is it that makes this project take so long for you? Is it the downloading of the entries, transforming them to some format that can be converted to PB .dic format,...? The reason I ask is that I presume that the Wiktionary entries are constantly being updated on the website, and I wonder how much work it would be to keep your version in sync with them.
