The PRO version includes what we call “Pro Features” which will be released over time to people who have the PRO version.

WindowTop PRO is being purchased by hundreds of people for its advanced Features:

  • A better dark mode – see example below
  • Smart transparency (Opacity Pro) – see example down below
  • Shrink live preview (Shrink Pro) – see example down below
  • Shrink right click menu – see example down below
  • Eligibility to commercial environment (unlike the free edition)
