it would be really cool to have checkboxes to uncheck the defaultly appearing text for the online version of the newsletter. It isn't really fitting into a theme / template of a newsletter and requires configuration inside settings page to do so.
Another checkbox for a similar text would be cool. Just easily add another text string everywhere for a default-unsubscribe message.
Additionally, from my point it should be theme'd or something..., I really would see the possible placeholders inside the editor. Well it shouldn't be a lot of work to implement an overview of possible placeholders including:
- Blog URL
- Blog Name
- Unsubscribe URL
- the already existing ones...
All in all its not that a big wishlist but I guess you'll spend some time for it.
