Feature request: reset timeout on mouse hover
I noticed on KDE, when mouse hovers the notification, it resets the timeout. The behavior is quite helpful, since in some cases, a user would likely want to focus on a specific notification (read the text, etc.) for a long time, beyond the default timeout.
Similar suggestion in the comment of #242 (stop the timeout instead of reset).
Workaround: dunst is versatile enough, the user can show the history notifications easily in various ways, so that he can read it again. However, it's better to be able to postpone the close of notifications without too much hassle.
That'd be a good feature. Somewhat related: #879. Although it's probably best to implement this feature on it's own.
