I would like an easier way to load the next/random images.

Right now you have to navigate down three menu levels to get to the "Load next image" command. (Correct me if I am wrong, it is not like this is a minor command...)

I would love an option to have this command as the main one when I double click on the DisplayFusion icon.

In alternative, or even better, it would be neat to have a shortcut commandline or something, so that I can create my custom button to load a different wallpaper background whenever I feel like it, without having to enable the hotkeys (I don't use them) or navigate three menu levels down (from an icon I keep hidden in the tray anyway).

(Before you suggest it, to use the titlebar button is not good either, because you want to be able to use the command when all windows are minimized and you have the desktop background in front of you.)

As I said, I don't use hotkeys, I need something controlled by the mouse.

Sigh. Please read the last sentence of my first post. Unless it is a custom not to read anything that goes on longer than a paragraph...

I would like the ability to go to the next image by double clicking on the tray icon as well.

The ability to change double click tray icon function, to be any number of commands would be great (add mouse buttons to the hotkey options) at the moment it just opens the wallpapers configuration page, which is not something that you realy need to access that much.
