Lots of bugs

Hello there,

I’ve tried quite a lot plugins related to tabs customizing, your plugin is the best one. It’s totally free yet lightweight, clean and no AD. But there are still some bugs that need to be fixed.
1) When editing products via ‘Custom Tabs’ option, the new tab cannot be saved. I can only add global tabs via ‘Product tabs’ option.
2) When updating a product which has a global tab, the product’s permalink will become tab’s title instead of product’s title, I have to edit the link manually.
3) It would be better that global tabs list by their nickname or reference number instead of their titles, because sometimes their titles are same, for example, ‘About Author’, which would be hard for the website builder to choose.

Regards,
