"Find similar" on selected files

[brand5884]

When you right-click on an image in browser-view and then click in the context-menu on "Find similar files" (or hotkey) the dialog opens in a blank state currently. I would like the selected files to already be in the list at the start, so you don't have to manually search for them again and add them to the list.

Additionally, I would like there to be a quick way to pick folders in which to search the selected images. These can be a number of previously used folders that you can pick from quickly, or/and manually saved. It takes too much time to manually search for the target folder every time you open the "Find similar" dialogue.

Also, If you want to search selected pictures in multiple target folders, then the search should not look for similar files between the target folders. There should be a clear distinction of what to search for, and where to search for it. The "Between folders only" checkbox does not allow for this distinction.

It would be nice if xnview would go open source, so users can add features they like to the software themselves.
