[Bug/Feature Request]: Add function to create files from shared content (for the "Save as" intent)

[NA0341]

Example: When sharing content of type text/plain, the following error occurs: An unknown error occured.

My theory is that this error occurs, because the "Save as" intent can only handle files that it receives.

It would greatly extend the functionality if it could also create files for raw content that's shared to the "Save as" intent. Therefore it needs to a) detect raw content, b) detect content type c) create a container (file) - possibly also with set metadata etc.

not sure what you mean here, can you tell exact steps for reproducing the issue?
