The gb.form.terminal is a new component providing a VT-100 terminal emulator control, that you will be able to put anywhere in your application. It will be used in the development environment instead of the old rudimentary console.

Here is a few features of that terminal emulator:

    Ability to use any font, even variable-width fonts displayed as fixed fonts. But then some characters too wide may be cut.
    Limited or unlimited history.
    Blinking text supported.
    Mouse support (currently in development).
    Line graphical characters are drawn instead of using the font glyphs.
