Using the chooser, you can make AWeb to open on the default public screen,
a named public screen, or let AWeb open its own public screen.
Default public screen
If this is selected, AWeb will open its windows on the default public
screen. Usually this is the Workbench screen.
If the screen doesn't exist when AWeb starts, the default public screen is used instead.
Clicking the button will pop up a standard screen mode requester. Here you can select a screen mode, width, height and number of colours.
AWeb will never load such a palette for screens with more than 256 colours. Those screens will be on a graphics card that is assumed to accomodate "enough" colours for all possible images.
Please be aware that 256 colours (or less) is not many. Although AWeb tries to calculate an evenly spread palette, still many images will look suboptimal. If you don't load the palette, the first few images look great, but later images may look even worse.
