These are my thoughts on TF3D....
I like it. I find that it has allowed me to access most features of my phone with greater ease than just the normal WM today screen. Scrolling to a tab to see or access functions doesn't really bother me at all. See I had been using Manilla 2D on my Titan for some time before getting my TP so I'm used to it. In ways TouchFlo has made these phones more a one hand device using my big fat thumb is especially useful at times. Of all the other today plugins & shells I find this one works the best for me....definitely when M2D had me at only 39% available RAM on my Titan!
Now I do strongly believe that it could be better. I myself would rather have the ability to see/adjust bluetooth & wifi from the today screen and have more of my calender visible as well. Even with TF3D Diamond Config I would like to have more options to make the today screen reflect what I want more. But the ability to adjust the order of the tabs, the one finger usability & the general look is preferable to me.
As with all the other UI's I've tried I expect to see improvements to TF3D come down the pike & I look forward to trying them out.
