In answer to your questions:
1) Yes, if a store image has been uploaded, that is what will be used on the coupons created for that store.
2) Not at this time.
3) The store image is uploaded from the Clipper admin dashboard and you do have the option to upload or link from URL as per normal WordPress media options.
4) It's just not currently an option.
5) This could be achieved through customization of the default theme on your part, however the theme itself doesn't currently have a custom form builder.
6) Clipper has a built in .csv importing tool as shown on the
Clipper admin demo. The usual WordPress import/export tools are still available, just not visible on our demo site.
7) Yes, this can be done through customization.
8) There are no user type options within the theme which can manage this type of access, and whilst there are WordPress plugins for this purpose, we cannot guarantee that they will be compatible with the theme.
Clipper is not encrypted, so if you are looking to make changes to the default theme layout/functionality this can certainly be done. Thanks.
