I mentioned earlier about a preview pane for each dir view instead of a single one via the One for all tree view. What would also be good instead is when mousing over an image, their is an automatic pop up view showing a view of the image or if not that in the preview pane when you clik the image the image appears in a zoomed in view that fits to desktop if larger or shows actual view. Their is a feature like this in XYplorer. This is the description on their site describing it
"Thumbnails of image files in one of three fully configurable thumbnails views.
Supported are PNG, JPG, GIF, TIF, TGA, WMF, PSD, ICO, BMP, and other formats. Optionally the pixel dimensions are shown below the thumbnail.
Thumbnails support XYplorer's unique and famous Mouse Down Blow Up functionality."
"Mouse Down Blow Up: Press your left mouse button down on a thumbnail and the original-sized image instantly pops up. Optionally shrunk to fit the screen, using high-quality resampling."
Here is the link in more detail over this idea
I will do my best ;)!
