I noticed that in the public list of Scheduled Maintenance, a newly created entry has no link to it's detail view. The detail view exists at /incident/ID
but one needs to fiddle out or even guess the ID.
Once such a scheduled maintenance work is done (e.g. the announced time-frame passed), the "x hours ago" text is linked to the incident's detail page.
It would be helpful to have the same link also on planned (future) maintenance work.
