It seems that Hype always keeps the track with an external resource despite the fact there is a copy of the resource in the package.
I would like to decide (with an option) that I don't want that an imported resource keeps a link with the original file and that it always uses the resource stored in the package.
It seems that such a feature is missing.
Should work like this.
Click on the resource > click on the button ‘Break link with external file’.
In the little info bubble, it says something like this ‘Hype will break any dependencies with the original external file and will always use the embedded version’.
This will allow me to assign the original external file to other projects by editing it, without the need to change its location on purpose (or the location of the Hype file) just to break the link.
