My initial impressions

First, I have to say that I really enjoy the beta version of Fitaly 4. It's been a real pleasure.

The new sliding paradigm works very well, and much better than the advisory lines, in my opinion.

There is one thing I would change, though. When sliding north to access the customizations, I like the fact that in the bottom rows, you have to slide a little further to get to the customizations. But in the top row, the menu appears directly over the letter. Most of the time I will just want to capitalize the letter, and not have to look at the menu items. (For instance, I slide north on h expecting a capital H, and I get 'has'.) If the distance from the key to the expansion menu were a user-selectable option, that would be ideal, in my opinion.

I find it confusing that sliding right or left on vowels shows a vertical menu, and continuing to slide left or right moves the selection up and down.

One other suggestion would be to allow sub-menus of sliding expansions. For instance, I could slide north on 'e' to get 'e-mail addresses', and then if I slid right, a list of e-mail addresses would pop-up. Or, sliding north on the ':' to 'emoticons', which could expand to all kinds of smileys, etc.

Or, maybe that's what the fish symbol could do.

Thanks for the good work. :)
