Suggestions about addons development

I’ve noticed if I use in a new addon the command
web-ext sign --api-key=xxx --api-secret=xxx actually uploads the addon but doesn’t send for review. I have to erase and upload manually on the page.
It would be great to be able to submit with command line.

And it would be great if the svg icons could be used for the addon URL too, instead of JPG and PNG.
Thank you

You can not currently submit listed versions with web-ext. I believe there are open bugs about that on web-ext that are blocked on AMO APIs.

What do you mean with this? Submitting an SVG for your AMO listing?
