NOW A NEW VERSION WORKING IN JB, GO TO THREAD http://forum.xda-developers.com/show....php?t=1838707, is equivalent to 1.0 version of this thread.
I have extracted the version of TouchWiz Launcher from SGS III firmware, and made it compatible with NON-OFFICIAL ICS ROM's for our Galaxy S, I tested with Elitemovil ICS ROM version 1.2 and it works, I haven't tried with other versions.
-Placed open folders so don't cover the Dock Bar.
-Now the App Menu Button can drag to any place on the Dock.
-Corrected an issue with the Number of Gmail Message, added permission for read the gmail database.
-Changed play store icon.
-Corrected an issue when populating folders in Applications menu in Alphabetical Grid, the last page has empty places.
-Changed appearance of the tabs, more like ICS.
-Replaced the Edit Icon in tabs for Play Store Icon.
-Removed the play store entry of the options menu.
-Changed the width of the open folder like ICS, the width is adjusted to the number of elements.
-Changed the position of the title in Folders, now is at bottom of the folder and centered.
-Corrected and issue with the edition of the folder name in Home Screen, when press the back button, text was empty.
-Now, the folder may be created like ICS, if you drag over an App Icon another one, then the folder is created, this only works in Home Screen, in Apps Menu Screen the creation remains the same.
-In Dock bar, you can create folders too, you must drag desktop icons over dock icons and vice versa to create folders, if you drag Dock icons over Dock icons, you swap places.
-When the folder has only one app icon then the folder is replaced with that App icon, like ICS.
-Adjust the size and capitalization of fonts in the App Menu title bars, (Tabs, Edit Mode, Downloaded Apps, Share Apps, Hide Apps)
-Removed the entry to create folders in Home Screen, from Home Eidt Mode Menu and Add Menu, to create folders use the method described above.
-Changed the Widget Search Bar to place the magnifying glass icon inside the box.
-Changed the Title of App Icons in Home Screen and Home Folders to display it in only one line and with ellipsis if the text is cut because there's no gap.
-Corrected and FC when creating a Folder in the Apps Menu, with more than two Apps.
-Corrected the thumbnails of app icons in folder icon, to take a separation between them.
-Added the Add Menu item in Home Screen Menu.
-Added Wallpaper Menu item in Home Screen Menu.
-Removed Add Folder Menu item in Home Screen Menu, now you can add a folder through Add Menu item.
-Activated wallpaper scrolling
-Modified App Menu so the title Apps it's not cut by the edge of the screen.
-Modified text size of the tabs Menu and Widgets and the size of the up bar when in Download, Shared and Hide Apps, now the line doesn't wrap when the number of selected apps and the text after it is greater than the space it has, this maybe doesn't occurs in English but in other languages it is.
-Works the folder creation, no FC.
-The functions of Samsung to set the Wallpaper are eliminated.
-In the Wallpapers Menu Selector, the textes are visible.
-The movement of icons with the move of the phone in SGS2 and SGS3 are removed because incompatibility with SGS.
-The number of unread sms-mms, gmails and missed calls is show over the corresponding Apps, Messages, Phone and Gmail respectively.
-Try, because is more complex, to put the Apps Options Bar of the Home Screen Up in the screen, so the dock bar can be visible to allow edition of the Dock dragging directly App Icons from Apps Menu. In this moment, you must put the App Icon in the desktop and drag from there to the Dock, so if you have no place you must create a folder over a previous App Icon and drag from there over the Dock. This reduces the number of steps.
