I've created a date renamer plugin, which allows the user to insert the mtime and atime of the file and, when compiled with libexif, the date when the picture was taken. I've choosen to not add some default formats, since the user will most likely create it's own and there was no clean way to put an extra combo in 2 lines of widgets. Anyway, it links libexif to the sbr plugin and maybe thunar-vfs should be added too, duno, seems to work this way. Btw, you could replace the G_PARAM_READWRITE with EXO_PARAM_READWRITE in the entire plugin.
