I just installed Mint 4.0 beta and it's looking great! Thank you for your work.
I have a suggestion for future/stable releases. Please include btnx and btnx-config. It's a daemon that send keyboard events when user clicks a button from a Logitech mouse. This has allowed me to get every button working (back/forward/side wheel/search button) in my Logitech MX Revolution. Besides it includes special support for MX Revolution, allowing automatic switching between fast/slow scrolling modes of MX Revolution's wheel. It also has some configuration utility to help people who don't want to edit config file manually.
Just have a look at it:
I think it would quite useful for Logitech user. I don't know if it would work with other mice too, but maybe.
Thank for your attention.
