Start with ALL images and flame effect variations preselected, then as they are displayed have the means to 'uncheck' them from future use.

Display the names of the current background and style in use whenever the Flame Control box is toggled on-screen (F1 or H).

Also, add two more options in the Fantastic Flame Controls: one to de-select the current background image in use, and the other to deselect the current style in use.

Also, add a boost/suppress "ranking/priority" (pre-selected at step 5 for no preference either way -- yet another note in the Flame Controls!) by pressing number keys 0-9 such that some background images (say, the burning desktop) occur more frequently than others as desired.

Combine the above two ideas: press keys 0-9 for background image priority preference when the screensaver is active, with "0" causing no further appearances (same as unchecking the box in the Configuration window); similarly use something like for the style choices.
