Thank you for reaching out to Atlassian Community and for providing your feedback about the Dashboard.
We are always willing to improve our products, so I went ahead and created a feature request to add the ability to show/hide this section of the dashboard. You can check the feature ticket at the following link :
I would suggest you to add your vote there, since this helps both developers and product managers to understand the interest. Also, make sure you add yourself as a watcher in case you want to receive first-hand updates from that ticket. Please note that all features are implemented with this policy in mind.
