What’s New in Perfect Browse 9.5

  • Perfect Browse Enhancement
    • Persistent Thumbnail Cache: Stores thumbnails are previews on disk so that when you go back to folder a second time it loads much faster. You can control the size and location in the preferences.
    • Improved Detail View: Our goal was to reduce or eliminate seeing pixelated previews in Detail View. It now generates a larger preview up front so you will see less pixelated previews. It also reads ahead and behind so that when you move between images there is no pixelation. It also continues to process thumbnails and previews in the background.
    • Improved Grid View: The thumbnail grid has been rewritten. It should be faster changing folders. You can also scroll through large folders with no detail.
    • Albums: Create and manage lists of photos that can live anywhere, similar to a collection in Lightroom.
  • General Enhancements
    • Hold down command and option when you launch to delete preferences.
    • Colorize and Invert options added to the Borders and Textures panes in Effects. This gives you more control over what color you want for basic borders like Simple and Emulsion.
    • Crop settings now sticky across sessions and modules.
    • 100% Actual Size option is now available in the Print dialog.
    • Brushes should now behave more like Photoshop. They feather equally in and out instead of just in. The brush profile has also been modified to act more like Photoshop.
    • Crash Logger: Automatically logs crashes and hangs and reports them back to on1.
    • Scratch Disk: You can now configure where you scratch disk is located. This is handy if your boot volume is a small SSD. Adjust this in the preferences.

Known Issues

  • Very small, low-resolution images may appear pixelated in Detail View due to too much upscaling
  • You may not be allowed to delete or replace a pasted folder after a long Paste operation is cancelled
  • Mapped Network drives on Windows may appear in Sources Pane with the name “[data]”, though they are correctly mapped
