Another vote for auto-login. Get rid of the 'logout' button in the place of the close one already. Nobody wants to log out, specially when they marked the 'remember me' check box. No other twitter client that I remember approach logging in and out like that. (also, check boxes should be square :P)

Even if I know it makes no difference, I unconsciously tap the task switcher button to then hit the X to close it. (bonus: this avoids the 4 (four!) step procedure to close it through its own interface) (Logout > confirm > exit > confirm)

Also this, not even counting the inconvenience, it's a security flaw. It recorded my password in the user auto complete dictionary. Seems Maemo doesn't treat that as a proper password field, maybe look into that?

And one last request: optify it please, just noticed that the executable is stored on /usr/bin. Seems silly since it can run from everywhere, I just edited the .desktop file to point to /user/home/tweego and it works normally.
