Possibility to link to an attachment in same/another MindMup from an attachment
I would like to see the possibility to make a link to another attchment in the same MindMup (or another Mindmup), from within an attachment.
In other words: Internal and external links to attachments.
This would make it possible for the reader of the MindMup to jump directly to (open) another attachment in the same or another MindMup.
If possible it would be nice if one could make it possible to link to a specific part of an attachment as well.
And at last, if possible to make the link open the linked attachment in a new browser-window (optionally) that would also be convenient (controlled by an attribute for the link).
It would also be great if these type of links also worked within the exported HTML and PDF.
