[One (M8) General] syntropic:
It's an option under the dreaded Xtended settings.

However, they are not icons (i don't believe...but I guess ineedone would know). I think xtended settings just let's you tint the original icons. I know this is something you can do with an Android app...there is a class (or subclass) which allows you to tint any graphic image with another color.

Now your nav icons [MENTION=5463312]smeejaytee[/MENTION]... Because they are two-toned (2 colors), I would probably guess that these are different icons.

On another note...

I was doing some things after I woke up and everything slowed to an unbearable speed. Everything was frozen.. I was about to hard reboot, but decided to wait. In about 30 seconds everything recovered somewhat, but it was still slow.

My first thought just as a temporary measure was to change some kernel settings in KA (i was plugged in so I wasn't going to worry about battery). But even after that, it was still slow.

I uninstalled a few Xposed modules that were really not necessary...But that didn't do much to speed things up. I then started thinking about background services.

About 3 weeks ago, ACR (the call recorder) started to show an icon in the status bar...meaning it was running in the background. First I went to greenify, but greenify couldn't hibernate it...And it wasn't even a system app!

I don't know if ACR was the problem, but it made me consider possibly trying to control startup applications. I tried a bunch of worthless play store apps, and finally found this one.

https://play.google.com/store/apps/details?id=com.autostarts.event

Which is very helpful. It requires root, but not only does it tell you when things start (e.g., during boot, immediately after boot, or once the system is running), but it tells you what event triggers that application to start.

I think most of the apps I saw were handled by greenify (eventually), but was really disconcerting to me was the multiple entries of system apps.. Just as an extreme example, I had 14 entries of Google Play Services starting.. They were all based on the same event. I had no idea why these existed nor how to get rid of them. The only reason I can imagine that they might have got there is because I often use apkmirror.com and download updates to Google play services (but you have to make sure you only download the ones with the "-238" extension).

Anyway, I disabled a ton of entries both regular and system apps... All I did was prevent then from autostarting.

It did speed my system up immensely after reboot. However I'm not sure if I caused another problem with the app (which could easily be fixed by enabling whatever I disabled in Autostart).

So far everything has worked great... A few things took a little longer than normal as I suspect they were system apps being launched for the first time (and since the non-paid Greenify doesn't affect system apps, I guess they will remain running).

But I just wanted to share this because I'm going to experiment with it for awhile. The really strange part though, as mentioned is the multiple entries... Chrome, Gmail, and a bunch of system apps were triggered by the same event but the trigger fit the event existed way too many times.

I'm also going to look at titanium backup to see if I can get any other information about this...
