I installed and played around with the app. It has some entertaining possibilities. Some things I noticed..
(Nexus one running rooted eViL 1.15)
-Words are tiny.
Suggestion: Show words that are used the most, maybe even bigger words based on how often they occur. (Doesn't seem to do that at this point.)
-Some times it includes the (1/3) (2/3) parts of the messages.
Suggestion: I'm not really a fan, perhaps removing them would bring a little more polish. Not a really a big deal though.
-Words do not fill the screen.
Suggestion: I have over 400 text messages but it only fills just the corners of the screens. There is a HUGE black area in the middle thats not doing anything, would be nice to try and fill the screen as much as possible.
I'm still playing with it, I'll let you know if I come across anything else.
