I Desperately need a "DUPLICATE" button on Global Add-ons alongside the EDIT & DELETE Buttons. DESPERATELY. PLEASE.

I have a large furniture website I am working on and the variants are the same but with different add-on pricing based on product type (chair/sofa/etc). I have LONG LISTS of add-ons that I need to duplicate many times and change the pricing to make global add-on variants.

Please add this feature ASAP. It cannot be that difficult and would save days of time and mitigate errors in manually entering the same list of 2000 fabrics etc multiple times.

apply_filters from WooCommerce is available for use on ```woocommerce_price_display_suffix```.

Currently, addons get multiplied by the quantity selected for the product. Would be great if there was an option to specify if addon prices should apply per-quantity, or only once regardless of quantity.

Currently, only one upload can be added per upload option, so a user must add as many upload options as they need. It would be best if multiple uploads could be added with only one upload option enabled.

When using Catalog Visibility Options(https://www.woothemes.com/products/catalog-visibility-options/) to disable orders, but show pricing, Product Add Ons options are hidden as well.

When you add a product level add-on to a bookable product there is an option to multiply the cost of the add-on by persons/blocks as seen here: http://cld.wthms.co/1dc2x/1rEWPCQi+

When you add in a global add-on there is not the same option available. This means that if you are offering a large number of bookable products that all offer the same add-ons you'd have to add each one in at the product level as opposed to using the global add on option.

Don't have a need for Group Name, but it's required, or the add-on won't show.

Add-ons don't do any sort of JS validation (yet) before allowing a product with add-ons to be added in the cart.

However, since the extension is deeply integrated in others that **must** validate user input in the front-end (eg composite products), it would be nice to have at least something 3rd party devs can use to know when an Add-ons input field has valid data or not, even at a very basic level (ie only to ensure that the user has made a selection, without any sort of content validation such as max char count, etc).
