Assign modifier key to extra mouse buttons [enhancement]

[neddy]

Description

It would be great if there was the ability to assign modifier keys such as SHIFT, OPTION or COMMAND to a mouse button. At the moment I see that you can assign SHIFT ANOTHER key, but not just SHIFT.

Rationale

Logitech have this option, I use it in games so that I can hold a mouse button to simulate holding the SHIFT key so I can bind things to SHIFT A or SHIFT B etc... I normally use this with the extra mouse buttons on the side of the mouse.

I would have bought the app if it had this function. At the moment my only option is to buy another Logitech mouse.

Cheers
