Neat trick to turn your C3 snappy as a "native application" (assuming you have the mindset thinking C3 is not as snappy as C2). Turns out the UI animations made things feeling delayed. Fortunately for us folks, we could turn the animation off!

If you like to go with a cleaner look, you could also un-tick "Enable UI effects". Voila! C3 is now snappy with a simple trick
