ideas that are not approved should still be visible to everyone in the Abstimmungsphase
In the Abstimmungsphase, ALL ideas should be visible, even the ones that were not approved. Let's discuss a design for that!
Ergo: As a user, I want to see all ideas so that I know which ones were disapproved of.
The reason is that an explanation is mandatory to disapprove of an idea. This explanation would be lost if it was not visible to everyone afterwards.
