(Note: The file extension 'dobedobedo' is registered as a humorous afterthought. The dedicated file extension for Be.app is 'be'.)
The above three files have but one (1) byte each. One character. Those characters are displayed in the windows.
Those three characters appear to be 'selected'. That's because they are.
Those three windows also appear to have different colours. That's because they do.
And please note: Those files are not 'rich text' - they literally contain a single byte.
And, as you can see in that brief clip, all that's done is the three files are dragged along the Dock and dropped on the Be.app icon. That's it.
Yet those three windows come up on screen with random window placements, window sizes, background colours, foreground colours, and unusual and very big fonts. How is that possible?
Do Be Do Be Do
Configuring a Be document file - note: not the application, but a file, as this is on a per-file basis - is just a matter of strolling through the menus.
You set alignment, background colour, character encoding, font, foreground colour, spell check, window frame, and your caret position and text selection, all saved when you save your file. On a per-file basis.
