project explorer more efficient

[marcelloh]

Suggestion(s):
When I create a BPMN diagram and add a couple of lanes, the lanes are shown on the same level as the diagram itself. It would be nice if they are visually children of the diagram.

The same with a user interface diagram and screens.
My tree is a very long one, just because of the many things a did. Sometimes finding something (without 'searching', but pure on it's name or location) is a crime to do.

Perhaps this could be part of a configurable option.
My workaround now is to create more subpackages inside packages (that are already subpackages....).
