Have you ever had enough to create shortcuts again and again on your desktop, type and retype the login URIs again and again ?
Just put them to the trash and install OpenSim Launcher !
Now you can choose the grid you want to connect to among dozens of others, and choose the viewer you want to use among Second Life viewer and RealXtend !
Never retype your avatar name again ! It reminds them for you. You may have different avatar names on each grid. Just select the grid and the corresponding avatar name shows up ! Your passwords are never stored anywhere for more security. You can also clear your stored identities.
