You can bind 4 different actions to each of your Octopus buttons. Each SHORT CLICK, which will trigger the Left Click / Right Click. Holding down the mouse button will turn into a Spinner. Here you can set 3 different attributes, by just moving your mouse horizontally, vertically and spinning your mouse wheel.

Also using the settings panel, you can set up you global Octopus behaviors. Here you can define the delay between the Single Action and Spinner action modes. You can set up Octopus Flash delay time, which will define the threshold of repeating an action you have done before.

Customize not just means the behavior of your buttons, but also the look and feel. Here you can decide if you want to use Octopus using Hold and Release or you just simply want to hit your hotkey and start Octopus.

If that is not enough you can turn the animations on or off, you can set your background and border color, your shadow/glow and text color. Also the length of the animations and you can also define the entire highlighted mouse over effect of your buttons.
