Happy to oblige
Note the little issue here, at least using the Swype keyboard, of there not being quite enough room, so the bottom gets cut off a bit. You can pull that font menu up though to increase the hit area for the bottom buttons.
I am not sure what the button on the top extreme right ('ab') is for; pressing it revealed that it can be set on or off, but I don't know what the effect is (it wasn't immediately apparent).
I also noticed a slight flakiness in getting the keyboard to display; sometimes I had to move the cursor around a bit to get it to come up. Also in the 10 minutes I used the application it crashed and quit on me once. This is an alpha release though, so I expect these glitches will get fixed.
What sharing options will there be when this is finished?
I'd be interested to know what we'll see under 'Settings' and how 'Synchronization' works.
Finally, I tried the search option, but while searching in note titles gets you results, apparently searching within notes is not (yet) supported:
All in all, I'd say this is looking really, really promising. Simple, slick, straightforward, with the functionality you need, and consistent with the overall UI paradigms of the N9/Harmattan. Wish all apps could be like this!
