@30knees thx for your feedback!
No idea, tbh. But all module files can be overriden in your theme folder, so everbody can design it like it fits best for him. It's not possible to find a perfect design for all themes ;)
Yes you can import them. This feature haven't been tested a lot, since I don't use loyalty module myself. You are right. It makes not much sense, to use native module and mine on the same time. I would decide for one or the other.
I haven't thought seriously about it. Right now it's not planned, since it's not so easy to implement. I have my module would become popular and the feature is asked multiple times, I will think about it.
Well with my module you can use all coupon features, which are available in TB. You just need to setup a "template". Just now I notice, that you are maybe talking about the loyalty points which are converted by the customer. I will improve this way, so you can use a template Coupon as well.
Yes. In future you can set it up, like you prefer.
Will be fixed in the next release.
