Hi, removing the http portion is not technically possible because that would make the links invalid in many contexts. Shortlinks are supposed to be portable and machine readable.
Removing the www subdomain is technically possible if your website is hosted from both domain names, or if your server is configured to forward requests to the www subdomain. In the latter case, your shortlinks would cause multiple redirects, and in the former would cause canonicalization issues.
If this is something you still want to do, I can look into adding it in a new version.
After taking a closer look at your website, I’ve decided this is a good idea. At least, I can make an option to remove the www subdomain. Hopefully it will be easy to do!
Feature implemented in v1.6. Marking resolved now.
