I've been using it quite a bit and definitely enjoy it. Nevertheless, as for more critical feedback, I would at least suggest one issue that deters me from wanting to use it for certain studies:

 

When performing a search, if the word(s) are not in the viewable field, I can't scroll without having to close out the search window. But after I do that, I have to start all over again. Meaning, I'd really like to be able to scroll when doing searches or have the display window populate some other way. All and all, it's okay for small/quick searches, but very cumbersome and time consuming for longer, more exhaustive searches.

 

Hope this helps (and makes sense:)!
