Tell us about your feature idea

When testing a site without a manifest, and using the manifest eidtor to create a new manifest, the manifest editor should try to pre-populate information about the app from the site itself, including meta tags and link tags.

Do you have an implementation or a solution in mind?

When there is no web manifest, look at the meta and link tags to get information like name, images, and description.

Ex:

In this image, I tried it with chat.openai.com, which does not have a manifest. Notice, it does have meta tags for title and description and link tags for icons. These can be used to prepopulate the appropriate fields - something that doesn't happen today

Have you considered any alternatives?
