How do I put the preview panel (images) on the left side below the treeview?
You can't, at least at the moment. The preview panel can only be on the right or on the bottom (or in a separate window as the standalone viewer).
Thanks Leo, but it is very necessary to free space, leave most usual and beautiful. Developers need to consider this.
Yeah, I'd need the preview pane on the left side (swap preview pane and lister) also.

Don't forget to send request to GPSoftware. If many people request this, maybe developer considers it
