POST EDIT:-
Forget that 'Inverse Spotlight' idea I previously had and just leave it as plain spotlight toolbar.
Final Spotlight mock-up:
Summary of changes here:
=A standard color choose command has replaced the 'RGB' controls -
Xntriq and
Helmut viewpoints.
=Added reset buttons for each input boxes of opacity,brightness,blur - knobs are much quicker to configure values with.
=Toolbar spacing in between each
=Added 'Shape Selection' such as rounded rectangle and oval - although Pierre has already stated that currently only standard rectangle is supported and no other shape.
Further final requests:
A.) Ability to click on each drawn Spotlight, during spotlight mode, and resize/delete the drawn spotlight by holding the 'Shift' key (Shift+left Click) - so this would mean it would execute a similar command as spotlight(s) 'undo' button already does.
B.) For 'Blur', after a user goes higher than '5' or '10' in blur value entered - then the inside surrounding-inline of each spotlight would blur too automatically, like this comparison; (xnview mp)-

C.) During choosing a color in the proposed 'choose color' dialog for "Spotlight":

A seconds delya might be best especially for larger scale images in where spotlight drawing would take it's toll on slower systems.
D.) If a user adds a 'Blur' to the spotlight then after that it would mean that no further spotlights can be drawn unless blur has to be undo first. Blur would be considered a final touch because of the potential CPU load of this effect.
======================
Previous REMOVED IDEAS that I have removed:
=RGB has been removed and replaced with a standard color picker on the toolbar.
=The 'auto label markers' idea is not needed here. If possible the 'auto label markers' could be completely separate feature for in a future XnView MP's "Effects" or separate tool.
=The 'Highlighter' feature is much better left for the Paint plugin MP or perhaps maybe as a separate XnView tool like how "Spotlight" is
