Can fork be represented by a diamond instead of a bar? Same way as it is implemented with "end merge".
If yes, then it would be perfect to have an opportunity to "style" both the start and end diamonds with a single character inside the diamond e.g. "+", "×", "○".
This MAY be valuable for representing BPMN diagrams using PlantUML activity diagrams and shall introduce more conformity to BPMN specifications.
