After few hour of heavy use of this TW4 port for SGS here is my feedback.
TW4 is clearly better than TW3. I even would say that it’s faster switching between home screens, scrolling in the app drawer.and doing a pinch in app drawer.
It has bugs. I had several FC without any apparent reason.
If you click the small X that appear on screen when you try to add a folder or new page to the app drawer it also gives a FC.
Hope someone knows how to fix it so we can have a better port of TW4 for SGS. By the way thanks who those who released the current one
