On Windows 11, the app windows and menus are rounded corners by default, while the accent color is widely applied in toolbar, menu, and thumbnail bar on Windows 10, too. These changes improves accessibility of the app, so now you can obviously see the current viewing image, the selected buttons on toolbar.
"Custom zoom" lets you set scale factor value of the viewing image a custom value. More flexible, more accurate for zooming feature.
ImageGlass auto-detects the multipage formats, e.g. ICO, TIFF, FAX, ... and loads all image pages. This may slow down the loading speed for some kinds of image, you also can ask ImageGlass to read them as single-page format by the experiment setting SinglePageFormats. By default, HEIC, HEIF, PSD are treated as single-page format.
<Item key="SinglePageFormats" value="*.heic;*.heif;*.psd;" />
Besides that, color management and printing are also supported.
You can make toolbar and thumbnail hidden in Full screen mode, you them in Settings > Image > Full screen.
