First: my compliments for this great plugin and all the work you’ve put in it. Amazing!
I’d like to know if it’s possible to use the Composer to make an kind of theme for all future newsletters. You know: compose a newsletter once and then save it somewhere – maybe as a child-theme – for future use.
The thing is, there’s a lot to be translated and it’s a bit of a struggle to do this every time.
And 1 more question: are you working on a possibility to pull ads (banners) form sites into Newsletters? Then the plugin would be perfect!
You can try to copy the HTML generated by the composer and keep it in a file or create a theme (see the documentation on this site) to future newsletters.
You can always duplicate a sent newsletter to create a new one, anyway.
