recently I finished a small plugin that supports your work within the Camunda Modeler by adding tooltips to various BPMN-elements. The tooltips reveal some technical properties that you normally need to open the properties panel for. Especially the tooltips for exclusive gateways help to quickly identify the outgoing conditional sequence-flows and their respective expressions (also working for conditional sequence flows starting at other element-types )
Here you go
