Patch Launcher Add or Delete Pages

Introduction
Someone in the forum talked about being able to add and delete pages in the Launcher app and I thought I would look into it further. They stated that they were able to add new pages and delete existing pages. Upon further investigation, they were correct. There is existing code, commented out, that will allow you to create a new launcher page or delete the current launcher page. There is a variable for the max number of pages palm set to 10. This value can probably be increased, but I don't recommend it and seriously, who would need more that 10 pages anyway, right?

Usage

 * The new page and delete page functions will appear in the launcher menu.
 * New Page
 * This will create a new page and move whatever page you were on to the right. There is nothing special to this page besides the fact that you now have a new page. You can drag icons to it just like any other page.


 * Delete Page
 * This will delete the current launcher page. Any icons on the page will automatically move to the page to the left of the page being deleted. If there is no page to the left of the page being deleted icons are automatically moved to the default page of the Web Browser.

Editing Process
/usr/lib/luna/system/luna-applauncher/app/controllers/launcher-assistant.js
 * Uncomment the following
 * Look for "appMenuModel" (line 29) a few lines below you will see a line that has "newpage" in it. On the line that remove the "/*" and on the line that has "deletepage" remove the "*/"
 * Look further in the file (line 120) for "switch" again remove the "/* and "*/" that surrounds the cases for newpage and deletepage.
 * Perform a restart and the new page and delete page options will be in the launcher menu.

Original discovery credit is unknown. Pyrognome tested and confirmed the new page and delete page functionality.

Rearrange Order of Menu Items

This is a fantastic patch that makes the launcher much more useful (along with the 4x4 icon patches), but I kept hitting Delete Page because it was second on the list when I was trying to List Apps. Then, the page that I was currently on would be deleted and I would have to go back through and move all the icons to a new page - frustrating for me. Therefore, I simply rearranged the order of the menu items to what was more intuitive for me. This is a small change to this great patch, and does not add or subtract any functionality.

Login via SSH

sudo -i //enter password to become root

cd /

mount -o remount,rw /

vi /usr/lib/luna/system/luna-applauncher/app/controllers/launcher-assistant.js //go to lines 26 and 27 and comment them out by adding '//' in front of them...to do this, hit 'i' to enter edit mode (you will see a capital i on the //bottom left-hand corner of the screen) and scroll over to the beginning of the lines and type '//'. Then, rearrange the five menu items to whatever //order you want...what I like best is below:

items: [ //{ label: $L('New page'), command: 'newpage' }, //{ label: $L('Delete page'), command: 'deletepage' }, Mojo.Menu.editItem, { label: $L('List Apps...'), command: 'listapps' }, { label: $L('New page'), command: 'newpage' }, { label: $L('Delete page'), command: 'deletepage' }, Mojo.Menu.helpItem ]

//This puts Edit first, then List Apps, New Page, Delete Page, and Help last in the menu //hit ESC to exit edit mode, and then type ':wq' to save the file (launcher-assistant.js) that we just modified...

mount -o remount,ro /

stop LunaSysMgr && start LunaSysMgr
