There's a feature that I would like to request for the View and Fullscreen modes of XnView, and that is the ability to go to the Previous and Next file using the left and right SIDE mouse buttons, because I use a 5 button mouse and I think that it would be easier and faster to move to the next image with a single click wherever the mouse pointer is rather than clicking the arrow icon on the menu bar or using the keyboard. I'm used to this feature on the default picture viewer on Windows, but I switched to XnView because it's way better than the default picture viewer on Windows 7. The side buttons I'm talking about are not the left and right click ones, I mean the ones on mouses with more than the standard buttons. The mouse on the next image has those side buttons (That's the mouse that I use):

There is already a similar request but that one is for the Browser view (Which I don't use): http://newsgroup.xnview.com/viewtopic.php?t=14280
Please XnView users support me on this request, you know you want to...
