The result of my design: 134 custom-made buttons (not counting spacers & labels)! My favorite button is the volume toggle in the lower right page. Here's what's unique about my configuration:

Consistent frame-based GUI with three button groups in frame:
TOP: device selection with trinary button states - pressing a pressed button in the main page of a device executes a setup macro with auto-power-on, etc.
LEFT: device specific buttons, e.g. TiVo: Favorites, Thumbs Up/Down, Slo-Mo
BOTTOM: “orthogonal” (e.g. X-10 & Amplifier are always needed independent media devices), or common functions (Keypad)

Modifier buttons, when pressed once, lead to an extra screen – when pressed again they lead back to same device

Eye pleasing “soft” design with fairly correct lighting (shadows, etc.) and well balanced colors

Simplicity – one page operation with most common functions

No confusing clutter (I put in time, date & battery for completeness only... I actually prefer it without those items, but it's easier to erase them than to integrate them later)

The activity signal is still visible, though barely taking up any space now

Background is defined on the System page only,... (more)

PNG Image Replacer: Perl script to replace some PNG images in PCF file with new images. Place old images to be replaced in local /old folder and their replacement images in local /new folder. png_swap.pl will scan a PCF file for images that match the ones in /old and will replace them with their counterparts in /new. Compares are done based on CRC32 values on the decoded PNG image content! (PENG saved PNG images are not identical to their imported sources due to differences in the compression used - took me a while to figure this one out!)
