Well, generally for small words there's a correction list, but it's not 
always complete and often there are words very different from the one 
I'd like to write, but not that one. So maybe it doesn't search in all 
the dictionary. I could I try that?
However my fingers are not so great...
If you want I can send you my dictionaries, so you'll be able to test 
them in a better way.

They're based on an online free dictionary, then while illume uses a 
list of sorted words, qtopia uses the same list converted to dawg using 
qdawgen (I don't studied a lot that format but if I'm not wrong [maybe 
I'm only mixing my ideas about a dictionary file format] it represents 
the words in some threes where the roots are the composed by the letters 
and every node could be both a father and a child. I guess that reduces 
the size of the dictionary [1,9mb vs  6mb] and maybe its analysis).
However they contain the same words!

Nice to ear! :)

Another thing I'd like to suggest you is that imho the backspace/space 
right-left/left-right dragging is too long. If you try writing using 
your thumbs you can notice that is hard deleting a word... Imho they 
should be more sensible.
