I installed it. Really nice. I like it much better than the cluttered Qstardict interface. very clean, less hectic. the definition displayed separately from the word list using the maemo navigation is much better also.
a BIG plus for me, no problems with MSCIM/Google-Pinyin input of Chinese characters like I have in QStarDict (I posted my problem in QStarDict thread a few days ago).

Only 2 small issues I noticed:
I have three dictionaries installed, Langdao CHN-ENG, Langdao ENG-CHN and Oxford Bilingual CHN<->ENG. It seems in the bilingual dictionary I can only look up English terms, if I type in Chinese words the defintions are always pulled from the Langdao CHN-ENG dictionary (I don't know if this was the same in QStarDict because I couldn't even input Chinese characters!). This may not be a problem with MStarDict, it could be the dictionary is not two-way, I don't know how to check.
Finally, a tiny tiny correction: there is an extra 'i' the word 'Preferences'.

Nice app. Thanks for your hard work rmoravcik
