18		-* **Comment Attachment**
19		-When computing a new layout for a diagram that contains comments (comparable to comments in source code), the comments often get placed far away of the nodes they refer to. This is because often the reference is not explicitly encoded in the original model. We have used a distance-based metric in the past to discover references automatically, but there are lots of ideas for improvement. This bachelor thesis would implement them, perhaps come up with additional ideas, and finally evaluate them in a thorough experiment.
