Lol ok,dumb question really.its probably all included ,iv posted a request in the rom thread

im liking v3.6 atm similar to 3.5,you got any new plan sfor releases,it would be kwl if you could get achotjans green signal bar in there as he said you have his permission and also the samsung galaxy s type gingerbread battery icon,would look sexy and very gb

You can flash the Addon yourself if you like it i dont need to include it. The ROM Style will stay same, all Theme modifications the Users can flash themself like they want it becouse everyone likes different i wont touch the Theme, everyone can flash what they want becouse i cant make a Theme everyone will like becouse thats just not possible, some like Blue, some like Carbon.....
BTW this doesnt has something to do with this Thread so please keep it clean

Hopefully you can create flashable zip for us.

---

Thanks Wolfbreak!!
You can edit buildprop w the flashtool or w rootexplorer, depending on which rom you are running, some of these tweaks may already be implimented!!
Zip file is too easy!! Explore research have fun.... just make a back up first....
Best regards,
Chris

Already did it manually using Flashtool and Root Explorer.
But for others who need quick progress, WB should create flashable zip for them.
AND
If can, maybe WB should consolidate addon such as Bravia Engine, FPS uncap, xLoud, Audio Fix, in one flashable zip.

Hi wolfbreak
I was changing the tweaks u had given
I was changing the below tweak
ro.product.multi_touch_enabled=true
ro.product.max_num_touch=2
mot.proximity.delay=100
and i found that max num of touch was 4 instead of 2 by default.... does this mean anything?

---

2Wolfbreak : according to this http://www.linuxinsight.com/proc_sys_vm_oom_kill_allocating_task.html I wouldn't do this "echo 1 > /proc/sys/vm/oom_kill_allocating_task". Placing 0 performs better, and prevents some unexpected FCs.

---

awesome man.>!!!

Thats a good initiative I was thinking of starting something like this for past two day but was wait that some actual dev to start it and i will contribute more.
ohk so here are one or two simple tricks from my side.
those who don't want to mess with install-recover.sh and prefer keeping the init.d style work
here is how you can enable init.d support.
add one line at end of your install-recovery.sh
Code:
# trying run-parted
/system/xbin/busybox run-parts /system/etc/init.d
some more tweaks which might overlap with the existing tweaks posted here...
http://forum.xda-developers.com/showthread.php?p=16441133#post16441133
Note : as usual non of the credit to me all credit to Dev's.

Request
Can someone point all guides of framework customization and howtos related to that at one place.
stuff like replacing the background image to adding a reboot option and simmilar stuff.
all links at one place would be just fine for new dev's (don't get angry if its already there and i missed it, coz there are chances of it too...)

---

So what do these tweaks actually do?
*improve* your phone will be the sarcastic answer, but forgive me if I won't blindly apply tweaks without having at least some idea as to what they are doing?

# Product
HTML:
ro.product.multi_touch_enabled=true
ro.product.max_num_touch=2
mot.proximity.delay=100
This tweak is basically a build.prop tweak which is making system aware of a dual touch capable system.
# Performance
HTML:
dalvik.vm.startheapsize=64m
dalvik.vm.heapsize=64m
dalvik.vm.execution-mode=int:jit
dalvik.vm.dexopt-flags=m=y
dalvik.vm.dexopt-data-only=1
dalvik.vm.lockprof.threshold=150
windowsmgr.max_events_per_sec=80
These are basically VM related tweaks first making heapsize 64M i.e. larger default is smaller. also this last line makes your system more responsive i keep something higher then 250 in place of 80.
VM Tweaks
HTML:
echo 95 > /proc/sys/vm/dirty_ratio
echo 20 > /proc/sys/vm/vfs_cache_pressure
echo 4096 > /proc/sys/vm/min_free_kbytes
echo 1 > /proc/sys/vm/oom_kill_allocating_task
echo 60 > /proc/sys/vm/dirty_background_ratio
echo 1000 > /proc/sys/vm/dirty_expire_centisecs
echo 2000 > /proc/sys/vm/dirty_writeback_centisecs
VM Tweaks basically change min free bytes and kill level's of application used internally by android for memory management.SD Card Tweak
HTML:
echo 2048 > /sys/devices/virtual/bdi/179:0/read_ahead_kb
echo 2048 > /sys/devices/virtual/bdi/default/read_ahead_kb
This is a simple tweak which specifies the read ahead buffer which is by default 128Kb effectively making your SDCard i/o faster.
Hope these could clarify your doubts remaining ones wolf or others might give a try to explain.

a flashable zip file would be nice

---

ive been trying to place my own tweaks within the install-recovery.sh file however when i flash zip the file seems to have changed however nothing actually takes effect. new to this side of things so could just be a schoolboy error lol. can say if i use the simple install-recovery.sh file from Z's uncap fps or even yours from your rom and flash it.. it all works well! if i try to edit any of yours and flash again.. nothing happens! wat am i missing?
