Description

It is quite common to see it in other IDEs to change the MimeType from a file which is open. For example creating a txt file as a temp file to discuss APIs.

That means you have not only JSON or XML but also comments and stuff which is not supported in that file and make errors.

But that doesn't matter, the created txt file is just a collection of all information.

So it must be possible to change the mimetype of a file which is currently open to change the content/text to text/json. This is not possible in NetBeans. It is just possible to change the mimetype for a whole filetype and that means global. But this is not the case here.

I created a plugin where I can read out the mimetype of a file and shows it in the statusbar. I wanted to change the mimetype, but the mimeType file property is just read only or is only changable when the file was created in memory whie the MemoryFileSystem.

I had a look into the code, at the end, NetBeans just take the extension and looks into the mapping where it was mapped against. So we need a functionality where we can change the mimetype temporarily.
