Requirements:
Internalz (pref Internalz Pro)
Basic knowledge of system files

My launcher pages get cluttered, so here is a way to make some apps invisible. This clears up space on your launcher, but the functionality of the invisible apps remains. This can be used to remove apps that you NEVER launch from their icon, these for me are: SIM toolkit, VPN, Uberkernel, Gesture Tutorial, PDF Viewer, etc. This process is REVERSIBLE.

Steps:
1. Launch Internalz

2. Make sure "Master Mode" is ON in the preferences menu.

3. Locate the app file for the app you wish to change. (System apps like PDF Viewer are usually in /usr/palm/applications folder, while installed apps are in /media/cryptofs/apps/usr/palm/applications/)

4. Navigate to the appinfo.json in the main folder for the app. Open this.

5. Here's the hard part. Under the icon information line, (looks like "icon":"icon.png") create a new line. In this new line, type
Code:
"visible": false,
MAKE SURE YOU PUT THE COMMA! IF COMMA ISN'T THERE, THE APP FUNCTIONALITY WILL NOT BE PRESENT.

Reboot phone, or just Luna. Enjoy you're newly cleaned and less cluttered Launcher.

To reverse:
Just remove the extra line from the file. Make sure all comma's and quotes are intact.
