Couldn’t find that wish searching the forum – please, Dmitry, ignore it if I’m the only one – but I think it would be a great leap for ganttproject to have breaks/voids between tasks shown in the summary tasks by dotting or dashing the line there. So if you only give out the summary tasks everyone in a project can see, where to have free time for other things and where to focus on the task (yet where to stay alert for news whether resuption will be earlier or delayed).
Hope the reatio between effort and achieved level of sophistication to be worth it, here.
Anybody else thinks this would be a great improvement?
