It works! N810 takes longer to index a large dictionary but once it's done it works like a charm (I have asked the developer if it is possible to preindex a dictionary on a desktop and then just copy the index file together with a dictionary; let's see what he says). Some of the windows are made for a larger screen but they are still usable.

Now, who would be willing to port toMOTko? It has a large collection of study lists (Japanese, etc.)
