Anyone here uses Sweeter Home 2? Share your experience?

I have been using it for a week. I feel it is smooth sometimes but most of the time, when I finish an app and press home/back, it takes up to 5sec to display the home screen again. I think it is that the home screen took a long time to be built up in background, which annoys me.

I already tried to trim down my phone so much to reduce the use of RAM but seems it doesn't help much.

How's your experience?

any tips?
