Hello, when on an 13″ tablet, I found it pretty comfortable to use just the River or Mosaic view, not “opening” the picture itself. This is especially useful for very tall images where the majority of the screen space is wasted (in landscape orientation).
However, this makes the experience worse, because it only shows lower resolution images even when on highest setting.
Suggestion: When zooming in on the Mosaic/River view to the point where the image itself is rendered using higher resolution than the available thumbnail, would it be possible to render the actual file instead?
