My two cents. I like the dictionary approach (mostly because of the feedback).
I don't mind typing an extra key (e.g. psal) because the feedback suggests it should be "psal" as soon as I typed the familiar two letters "ps". As long as it does not involve shift/sym/alt, IMHO it is user-friendly.
(That said, I don't like Alt-q for 1 as always!)
The '.' works instead of ':'. That's good.
Typing "psal 21.1" shows Psal 2:11 as top, followed by Psal 21:1. With the down key I can go to Ps 21:1 quickly. IMHO, I appreciate that there is no context text, just a list of plain ole references is easy to use.
That said, I don't like GW translation too much... NASB/ESV with this dictionary navigation will be great! Will pay for it!
