803  There are several unresolved issues with the user interface  There are several unresolved issues with
804  described here:  this type of user interface.
805    For instance, allowing the user to have several
806      - multiple main views (cf. transpointing windows)  separate "focused nodes" at the same time
807    is necessary to allow linking; there are several
808      - combining buoys  possibilities but the choice is important.
809    Also, the buoy algorithms need more work:
810      - buoy geometry problems interacting buoys  if there are two buoys simultaneously showing
811    regions of a document close to each other, they
812      - user editability  should probably be combined. Also, if anchors are
813    very close or coincide, the buoys should be
814      -  pushed away from each other.
