You can't see other plugins in TouchFLO because TouchFLO 2D/3D is a Today screen plugin. Uncheck it in your plugin settings and it goes away and you can choose other plugins. Either it works for you or something else works for you. No big deal. As for chaniging fuctionality in TouchFLO, just be patient, it is being worked on and is making progress.
If you are worried about buying a Diamond or Touch Pro because you don't want to loose functionality, don't worry, you can uncheck the plugin and have a normal WM 6.1 Today screen where you can install any plugin that is VGA compatible.
Just chill people...it's a phone.
