SGViewer 1.9.1 is buggy

[Wepver]

SGViewer 1.9.1 plug-in does not work properly on folder change when it is already displaying a picture and the opened folder’s first file is a picture too. If previous/next button is pressed then it displays the last image of the previous folder (not the current one). By the way, it would be great to be able to zoom in/out an image by the use of left mouse button + scroll (Like the no plug-in image preview mode)

we dont develop plugins ourselves, but it might be due to something on our side, so we will check it.
