[One (M8) General] high_voltage:
A9 camera app has slowmo and timelapse both working... jw 5.4 is total A9 port using A9 drivers etc so all working good as it should + they polished it a lot. Xposed is know to get you bad battery life even only installed wtihout modules, so I don't advice using it in any m+ eans if you care about battery life + performance as many complained to get slugish phone using xposed.

Try it, seriously... just stock jw 5.4 with EX 6.0.3 in aroma and nothing more... play around with it, shoot with the A9 camera(btw, HDR photos on it are instant... no processing(as it doens't use the duo camera, but if you want the duo you can use the M8 camera app in the rom), sense 7g is more lightweight... most of the time I got 250MB more free RAM than vs stock sense 7 and that makes a huge difference... also read/write speed are insane, especially after the rom settle random write goes to 6-7K iops... vs 4K stock and 3K leedroid. Battery life is insane compared to other roms. Really... it's just good. Quick settings are cool and yes - you can add apps there as [MENTION=2438435]gameovr[/MENTION] says... really cool tbh. Also sound mods like JBL and HK + stock is M8 boomsound. Got also sense 7 but that's worse as it's M9 port + more ram hungry. Also the A9 port have sooo good recent apps and the animation is to pull down the current window to it... it's so pretty and fast compared to M8 variant of it... really on a new usable level, I like it more than tiles that I used on M8 and a lot more than the it's M8 counterpart.

Yes, you can add QS from the settings menu... as for the HTC 10 port - few things to note:

1) A9 is A LOT closer in hardware to M8... screen size, resolution, processor power, RAM(it got 2GB ram variant in the 16GB internal)

that lead to a lot more polished and runnable software on our M8

2) The A9 port was developed for some time while the HTC 10 port is still new.

I am sure they will get it up to speed, but I am not sure they will ever make it lightweight as their A9 port that have great battery life and performance because of it. HTC 10 have a great deal of more hourspower than our M8... totally twice faster processor, screen resolution is also different, the ram is twice more at 4GB... just no comparison and that leads to software that is too heavy for our phone so full port at that stage if not heavy modified is, I am afraid, doomed to run good on our M8. Sadly they discontinued their A9 port, but it's still a decent state. Will use it more, but yesterday I had 5h SOT with 13 hours on battery and you know what? 50 percent battery left. :) True, I read a lot in chrome, but I had also youtube, facebook, viber and messenger + I used it some at light conditions also. Take it as you will... but if I use the phone like that at the evening at home I am sure I will get 9-10h SOT. Also standby is great - I had a team building for the weekend without any charger... took a lot of pictures, didn't even restrict google play services(that ***** drained 25% of the whole battery life?! LOL - kill it with fire!) and returned home after two days with 36% left(if I had disabled mobile data use for Gapps I would had around 50), 4G is working as it should... apps stays more and longer in the RAM and just... well, all the good positive words towards it that flooded their thread and M8 forum was and are true.
