Frames can be used to display a bitmap that has no function, draw simple lines or colored rectangles, or group other buttons and frames together as a single movable object. The huge amount of memory available on the TSU2000 means you may have to work quite hard to use it all. So, the actual maximum number of buttons per page is, on an technical basis, effectively limitless. However, the display memory on the Pronto represents a more grounded reality, with the tangible number being around 80-110 buttons per page before the remote runs out of display memory and will spontaneously reboot. Surprisingly, some folks have come across this limit without meaning to.
Some screens can contain a lot of buttons.
Since ProntoEdit can only work with or select one button at a time, complex structures such as keypads and transport controls must be grouped together with frames if you plan on moving them easily. This is a somewhat awkward process - when moving a framed object you must click on an unused portion of the frame, otherwise you move the object inside the frame. Starting from scratch. If you plan on creating a design completely from scratch, loading a bitmap manually into each and every button would take much too long. So, ProntoEdit includes two ways to quickly add prepared buttons.
