Zoom Options Dialog
|Latest release||2.0 / 2006-05-04|
Zoom Extender allows you to configure what combination of shift keys and mouse clicks are used to zoom in. It is especially designed for those without scroll wheels, making it difficult to zoom in and out. Originally inspired by Google Earth's double-click to zoom, it has expanded since then to become much more versatile.
However: twobeds.com is down at the moment. It's down because it crashed. As twobeds was a free service hosted on The_Beans personal server there was no backup, and it won't be back. Hopefully Nova has his own backup.
