Camunda-modeler: When selecting a Sequence flow of the Label for the Sequence Flow, highlight the label/sequence

[StephenOTT]

__Describe the Problem__

When you select a Sequence flow the label should also be highlighted so you can quickly tell which label corresponds to the flow.

When you select a label, the sequence flow it belongs to should be highlighted so easy reference to which sequence the label belongs to.

When you have complex processes with lots of flows, the labels can be mixed up, especially when moving and resizing

__Solution Sketch__

Show a fine, dashed line when hovering a label that links the label to the labeled element:

Depends on https://github.com/bpmn-io/diagram-js/pull/290

Sounds like a good improvement. Highlighting on mouseover only may be a snappier solution, too.

[StephenOTT]

Yes that would be great. 👍

• [ ] highlight label(s) when selecting sequence flow
• [ ] highlight sequence flow when selecting label
• [ ] + mouseover

This needs additional thought and work to be a proper feature that does not confuse users.

We postponed the implementation in diagram-js (https://github.com/bpmn-io/diagram-js/pull/290) to a later point in time.

Discussed a new approach: Showing a dashed line which indicates the reference between label and sequence flow (or any other element?)

I think that would be an amazing option :rocket: :fire:
