Before you update, it is recommended that you back up your settings: 'Launcher Setup->More->Backup and Restore', choose 'Backup settings' and 'Backup desktop icon placement'.
See the ADW Guide for more help:
Key features of ADW Launcher Free present in Legacy Launcher:
* customizable number of desktop home screens
* customizable drag&drop action buttons
* ADW themes
(See the webpage for a more complete list of features. Note that some features have been removed, such as the hidden dock bar.)
ADW Launcher was developed by Anderweb and a team of developers:
These permissions were retained from the original ADW source code and have not been significantly changed, and are standard for Launcher applications.
If your installed ADW Theme looks weird, make sure you have not selected 'Override Colors' in the drawer and application tray.
If you would like to install a theme with a custom dock background, remember to unhide the dock background.
I did not enable the importing of ADW Launcher settings, but you could try renaming the backup xml and db files to the ones used in this application.
If you have an extra high resolution device, this launcher will not look optimized for your device. The original application was originally made for 800x480 screens and lower, so there is little I can do to make things work better for you.
If this does not fit your needs, I recommend that you try:
ADW Launcher EX
ADW Launcher Free
Go Launcher EX
Unless otherwise noted, it is recommended that you update to the newest version available.
