What would be the process to have an older extension developed by Xavier upgraded to include permission restrictions? I didn't think it would be appropriate to bump a post that old.
If the option is to create a new extension, below are the requirements as I see them.
An extension to add iFrame attributes to Flarum.
The extension will have permission settings so that only selected user groups are able to include iFrames in posts.
The project will have MIT license and available on GH.
