For the last couple days I've been rewriting PicoGUI's user input subsystem almost from scratch. Today I got it duplicating most of the functionality available in the old input system, so that it's actually somewhat useful. It has some cool features... the system is based on modular "input filters" so that any pgserver component or client program can intercept, modify, and forward triggers before they reach widgets. So you can have client-side T-9, Kanji, or other input methods. The cool feature pictured here is multiple cursors. The mouse cursor has been abstracted farther, so that it's an object owned by the input driver. Here I have a USB mouse and a serial mouse, each with their own cursor operating independently.
