    Major Update: Ostendo v4.0 Released!

    Faster, smoother, and more reliable across the board... plus a new Collections feature for Ostendo Pro.

    What’s new for everyone:
    🎨 8 new tile color options
    ⚡ Major performance improvements
    🧠 Smarter thumbnail detection (fixes missing Tiles)
    📐 Improved layout system (less overlap, better sizing)
    📢 New announcement system... hello!



    Introducing Ostendo Pro, your thumbnail moodboard.

    Instead of downloading thumbnails and saving them to random folders on your computer, Ostendo Pro allows you to collect a thumbnail with a click, it'll be waiting for you in your Ostendo Pro dashboard!
    From there you can add tags, sort, filter, and export thumbnails with ease!
