Logitech program'd mouse buttons to switch w/ Apps?

[starcrossed]

I have a Logitech MX500 mouse that I love for its many buttons, but I've noticed that there is some other companies that in the software for their mouse have the option to program mouse buttons for specific apps. (For example, the mouse reacts differently in iTunes and Safari and so on), but in the software from Logitech they still have yet to add this feature. I was wondering if anyone knew of any good ways or 3rd party software to be able to add this feature to my mouse and computer. I've thought about switching my mouse to the other company's but they don't seem to have nearly as many buttons as my Logitech, so any advice would be greatly appreciated. Thanks.
