controlP5 is a controller library for processing that works in authoring, application, and applet mode. controllers can be added to a processing sketch itself, to separate control windows, and can be organized in tabs.
all controllers are drawn on top of a processing sketch. several key combinations allow the user to show and hide the user interface, save and load. controlP5 setups can be saved and loaded locally or to/from a server.
the position of a controller can be adjusted during runtime by moving a controller with the ALT-key down.
the controlP5 source code repository is available at sourceforge at

export to applet

since the security regulations for applets are very high and strict, you need to make fields and functions that you control with controlP5 public in your code.
