Yeah, over time we'll add configuration persistency as well as some other obvious features.
Remember, it's free and, once we get it to serve its primary goal (from our standpoint) its further development will be a function of donations and commercial licenses.
As things are, it is only out there as a byproduct of our dictionary and Bible developments...
We may make persistency only available for registered users, for example.
Still haven't decided on that, we first want to make it reliable across the board and then figure how much interest is out there so that we can decide how much resources we can allocate to it.
In its current form it is mostly a byproduct of our dictionary and Bible development efforts...
