Callipeg is designed to operate the iPad gestures possibilities to make your use of the app as quick and intuitive as possible.

A single tap uses or opens a tool or feature.
Tap on any icon to use the tool or feature or to open various panels.
When a text is orange, this means that it is either selected or that you can tap on it to activate it or change the value or parameter.
Double-tap on a text to rename it. You can rename the shots, the layers and the palettes. You can also use the double-tap on a number to open the numpad and enter the desired new value.
