[Galaxy Tab 2 General] bluecarbon:
This is for P311x, but may work on other devices

Well, this is a how-to topic for some questions that I see asked periodically. These steps are how I achieve my desired results, feel free to call me out on insignificant steps, post alternatives, or tell me if I'm wrong.

These are the steps I take, and are for the P311X they may work on P3100, but I'm not sure. This is merely meant to be informational, and as I haven't made any of these apps, or scripts, I'm not sure as to long-term effects. Furthermore, I am trying to be is as accurate as possible, but I am not responsible for damage to your device, try these at your own risk.. With that out the way. I hope this helps.. :)

OK, How to use your SD-card for apps:

There a number of ways, depending on what Rom/Firmware you are on.

Pre-4.2x (IE. 4.1.x)

Personally I use the SD-card swap script. It works well on the P331x.

It is found here: http://xdaforums.com/showthread.php?t=1961097

You can follow the Directions there, as that is what I do. He already fully explained it and I do not want to step on any toes by copying the steps here.

This will only swap your data mount, not your system, so it should not break anything.

On 4.2.x:

Use foldermount found here: http://xdaforums.com/showthread.php?t=2192122 as it is the best option that I know of:

It will not completely swap your sdcard, but it will allow you to move and make links to large folders of data, such as obb folders, from your internal sdcard to your external, which could save a person gigabytes of space.

The steps I take are:

1.click add to add a “link”.

2. Name the link something that will identify it well.

3. Chose your source directory: and navigate to the directory you wish to link. Note: you can only link individual obb folders, not the whole directory. Click the check.

4. Choose your destination folder and either create a folder on your sdcard to move it to, or let it do it for you and click the check.

5. Click the check at the top

6. I just let the app move over the data for me, but you can do it yourself if you want.

7. On the main screen either click the pin or the circle plus symbol. If the pins turn green it is linked, if not trace your steps and make sure everything is being linked to the correct folder.

8. Repeat up to 3 times on the free version and as many times on the paid.

How to hide your navigation bar on stock:

What I do is:

1. Download LMT Launcher from here: http://xdaforums.com/showthread.php?t=1330150 This will give you Pie navigation controls.

2. make sure you set it up, by making sure touch services are started ,and that it is set to boot if you are going to hide your navigation bars at boot, otherwise how will you navigate?

3.Use GMD hide bar, from the Google Play, to hide your system bars. I use the “busybox method” in the settings and set it to run at boot. You can toggle the hidden bar either by widget, or from the app. I have heard that there are free alternatives, but I'm not sure how well they work, because I have never used them.

Here is a thread, but he says it is for an older, unmaintained version: http://xdaforums.com/showthread.php?t=1769761

Fake multi-windows. Note: as of writing, there is not any true multi-window ability.

This is easy and does not require root.

1. Download Sidebar or another similar product from Google Play. This will allow one to launch apps from a user defined list, simply by swiping from the side of the screen. You can setup where you want to swipe, how sensitive the trigger area is, etc. This will also allow you to launch floating apps, such as a browser, media player, calculator, etc. in its own window, over running apps.

2. download some floating apps. I use Aircalc (a lot), floating browser, and popcorn player primarily.
