Attributes support

Hi there, i really love the plugin, it has almost everything a shop needs! Great work. I was about to buy the Pro (5 sites) version but there are some major things missing (for me that is) Attributes filter. This is the most crucial, will you consider implementing it in feature update? And when if i may ask. Sale bubble. Some themes, like Woodmart for example, have the option to display the discount amount on a bubble. Other plugins have this option and is showing just fine. i could not find it in the settings. Is it possible to show? Thanks
