[Motorola Droid RAZR] Ohmster:
Yeah, I really answered both of your questions, in full. Modules are superior to apps because they are, I don't know how exactly to explain it but this is close enough. Xposed Modules, as apposed to apps, are "embedded into the system" and can interact with it in ways that an app cannot. You will see this for sure with a custom kernel like JBX, now, with modules, you can overclock the CPU on a kernel level, decide how aggressive the memory and CPU management will be.

Yeah, I did it again. Way too much to read. So if in a hurry, find the orange links and read around them. Use them. Most of the text is detailed instructions if you need it. These modules can be overwhelming at first. Skip the Greenify part if it is not relevant to you.

Greenify is a perfect example of why modules are superior to apps. Before Kit Kat, I had apps running at all times, fighting for crucial tidbits of memory. Made my phone slow to a crawl. I could not open dialer or maps in less than one or two minutes. Facebook, cloud drives, stupid games, *everything* would refuse to exit, would run infinitely, and degrade the entire system. Task Killers did NOT solve the problem. They would kill a whole bunch of running, non-essential or necessary apps immediately, and they would respawn, ...immediately. Task killer would kill them again, and again, and again, and they would never stop. Greeinfy would put them to sleep, and keep them sleeping, so as to free up crucial memory and the phone was fast again. I purchased it immediately. But with Kit Kat (CM11), Greenify was "out of a job". Everything it was assigned to put to sleep, were already sleeping by Kit Kat. Greenify actually serves very little, if any purpose on Kit Kat anymore. So, as much as I love it, paid for it, and want it, there is no point to running it anymore, so I no longer run Greenify. How can you force Facebook to sleep when it is already sleeping? It is like running two, very good, paid antivirus programs on your PC. NOT a good idea. They essentially do the same thing and "fight for king of the hill".

To keep your screen lit, on a per app basis, an Xposed module would be better suited to do it as you are not adding another app to the system. Well, some of them do come with an app interface for management. Modules are system apps and have first dibs on everything. So, for the screen lit issue, install or open Xposed Framework. Tap the Framework button, install/update it, and reboot. Open the same "App" again, Xposed Framework and tap Download. Find App Settings, download and install it. You want the super cool CPU monitor? While in Downloads, find Cool Tool, download and install it. Go back to the main page of Xposed Framework. Tap the Modules button. Put check marks into the new modules that you downloaded check boxes to activate them. Reboot to activate them. Open Xposed Framework again, tap modules, tap each one and configure to your liking. You will have to reboot one more time to fully activate them. Cool Tool will begin to work right away, giving you glorious CPU, memory, and other settings as real time graph, labels, and gauges. You will see them right away. On top menu of Cool Tool, go to the extreme right and tap Xposed". Tap "Inject into status bar" to make it behave like a module and not an app. Choose the position, I like "right". As you make these changes, they will appear in real time in the status bar. To fully customize, go to Main for the graph. Pick what you want as a real time moving graph, I like CPU Usage. Then go to Labels, these are the actual readings in words. I choose CPU usage, CPU frequency, and Available RAM. Now to go Gauge and tap the gauges you want, I picked CPU usage gauge and RAM gauge. That will replicate what I have. But there are MANY, MANY things you can monitor. Pick what you want. play with the other settings and watch what appears on the screen. You will be overwhelmed at first so I gave you my setup advice to get you started. But feel free to experiment.

I promise this is what you want. Forget the app, use these modules. Since there are so many modules, I suggest you browse them on a PC, see what you like, then install from the Download button in Xposed Framework. Click module box to activate, reboot to activate, then tap each one to choose what it does for you. I will give you a list of ALL modules for you to browse on a PC browser, easier that way to find what you want. Pick stuff that says "Kit Kat" or "KK". Do NOT pick modules for specific roms or devices you do not have.

Browse the Xposed Module Repository List

There are 24 pages of modules. Get a cup of coffee and plan to spend some time here.

Cool Tool is THE most awesome system gauge I have ever saw and even dumped my paid for app, Micro CPU Monitor for it. My previous CPU monitor was a paid for app and Kit Kat often put it to sleep so it was never "always there" for me to see if my phone was bogged down. Cool Tool, as a module,

is always there for me to see

.

Below are some of my modules in the Module list, showing the check box to activate it and showing Cool Tool installed and one showing where Cool Tool is.

This is all you need, I promise. Just try it! Good luck. :good:
