I'm with you, Bruno.

These days, WEP and WPA keys can be pretty byzantine, and I'd really like to see them optionally show clear text. To answer your question directly: No, it's not an option in this version of the software. And the aforementioned 2.0 feature of the last character hanging around for a second or two is utterly useless.

The following things need to happen on this thing to make entering WPA keys more friendly:

1. Optionally show clear text characters when entering WPA keys.

2. Make the caps lock feature (double-clicking on the shift button) stay "sticky" when toggling back and forth between the numbers and letters panels. If you don't understand why this is needed, try entering the following as a WPA key: CD19DF45ABBA5B5CD5A1

3. When entering passwords or WPA keys, it needs a different keyboard entry panel that includes numbers and letters on the same screen so that you don't need #2 above.

Without these features, entering WPA keys is do-able, but a huge pain.
