BG Version 2.1.1 - Thumbnailer on Win10 64bits :
1) Thumbnailer creates a DOUBLE thumbnail on the page ! So I have always to delete the extra one ;-)
2) Needs to TYPE IN a thumbnail name AND the .png extension for the thumbnail beeing created.
3) IMPROVEMENT : While correcting 1), it would be nice
a) to have AT LEAST the .png extension by default when entering the file name
b) or even better, having AUTOMATIC NAMING of the thumbnail image by
adding something like "_BG_thumb.png" to the original file nam
c) maybe even a checkbox to activate automatic naming
