any downsides then to enabling HWSYnc?

Some people experience random reboots.

Turn it on and test it. If you dont experience any random reboots, then leave it on and enjoy the little extra smoothness

If your phones starts to crash and reboot, turn the setting back to disabled

I think it runs battery out faster than before. But it's been few hours of testing. However, it improved responsiveness, I think. At the moment the conclusion is that it works as expected. If it causes no general crashes it could be imported on future CSSU updates as an optional feature. I see no reason not to do it if it is quite stable and always remains optional.

all other program load fast exept for filebox...no problem on my configuration cause filebox load fast before i install CSSU but now it doesn't...i use the same(before & after installing CSSU) MicroSD 8Gb class 4 with 6.4Gb left while MyDocs have 20Gb left...my start folder on my filebox is home/media....stock filemanager runs smooth & fast...

I think people are forgetting that the main point of CSSU is to replace/update elements of the OS that cannot be normally replaced from the repositories.

At this point I'm not even sure that an open source recode of the battery applet should be part of the CSSU - it could just as easily be a seperate package, no? Not only does it keep the CSSU confined only to the stuff that needs to be in the CSSU, but it lets people replace their battery applet (or not, if they so chose) on either a CSSU'd or not-CSSU'd device.

That's not to say I'm against the battery replacement, and I like the idea of seeing mAh along with the percentage, but I can't forget my give-users-choices mantra, and all the related ideas, just because I personally like the possible-future-direction option.

Anyway, the main point of what I'm saying though, is this hardware sync thing can go suck it. Even if it makes the device smoother, it's not that amazing. And animations do look slower with it, even if they are smoother - users who don't like the cahnge shouldn't have to deal with Theme Customizer or manual tweeks of their transitions.ini file just to make their stuff look nicer again.

At any rate, the CSSU isn't about giving every little possible tweek that someone might want quasi-official default-ness. Less nr_requests and lower swappiness (and other tweeks) seem to help quite a few things too - but there's a reason why CSSU doesn't include those - because it's already easy as frak to do it by default.

Power Kernel is better than stock too, yet no one who's thought it through would want to force everyone to upgrade kernels just to get CSSU fixes/patches/goodies.

And if you want hw sync or whatever, it takes you five seconds of file editing and a reboot to do it. There's no reason for the CSSU to include it by default.

i was having major problems with filebox after 14.1 cssu update, so much so that i re flashed.

after the re flash and re installation of the cssu EVERYTHING works brilliantly filebox is rapid, microb facebook status updates work (i haven't had any problems with it ) have only had one modest crash and rotation works a lot smoother (i did copy my transitions.ini before re flash so i know its not just because of a standard cssu transitions.ini)

Here you go my personal transitions.ini. This will help improve your device animation and rotation is very similar to those on Android.
Fast rotation and fast transition. This transition is best with/without HWSync. Hope you like it. If you do like it then do Thanks me click the button.

Incase those who'd not have a clue of where to do it. Here is the detail:

But what do you think about "slide buttons" to answer a call? Just like s60v5.
And one problem - after installing cssu i can't change icon size in theme customizer, is it normally?

Please install slide2answer in extra-devel.

The app is there. Stop requesting and start exploring

thanks for the tip, this makes app and app switcher zooming really beautiful.
