**As** an OpenProject user
**I want to** be asked for confirmation when I click on the Begin of the insertion**MarkEnd of the insertion Begin of the deletion "MarkEnd of the deletion all as Begin of the insertionread**End of the insertion Begin of the deletion read"End of the deletion button in Notification center
**so that** I don't accidentally mark all unread notifications as read when trying to mark just one of them as read

### **Context**

Multiple users have complained about accidentally losing their set of unread notifications when accidentally clicking on the Begin of the insertion**Mark allEnd of the insertion Begin of the deletion "MarkEnd of the deletion as Begin of the insertionread**End of the insertion Begin of the deletion read"End of the deletion button, having confused it for the Begin of the insertion**MarkEnd of the insertion Begin of the deletion "MarkEnd of the deletion as Begin of the insertionread** button.End of the insertion Begin of the deletion read button".End of the deletion Whilst there is a minor difference in the icon, the relatively small dimensions make it hard to distinguish, and the difference is even less apparent when scanning.

### **Acceptance criteria**

When the user clicks on the Begin of the insertion**MarkEnd of the insertion Begin of the deletion &quot;MarkEnd of the deletion all as Begin of the insertionread**End of the insertion Begin of the deletion read&quot;End of the deletion button:

* Display a modal dialogue:
* Title: &quot;Mark all as read&quot; (no divider)
* Text: &quot;Are you sure you want to mark all your unread notifications as read? This will empty your notification inbox.&quot;
* Action bar (grey, two buttons on the right side)
* Danger: &quot;Mark all as read&quot;
* Secondary: &quot;Cancel&quot;
* The &quot;Cancel&quot; button cancels the action and closes the dialogue
* The &quot;Mark Begin of the insertionallEnd of the insertion as read&quot; button marks all unread notifications as read

### Out of context

One larger, more general solution to this kind of problem is to introduce a software-wide undo feature (a toast like: &quot;All unread notifications marked as read. [Undo](https://community.openproject.org/#).&quot;), but this is outside of the context of this mini feature.
