Hi Eduardo, I'm a UX Designer at GitLab working on issue boards. If you click on the issue title, it will open the issue in a new window. If you click somewhere else in the issue card, it will open the summary sidebar. But I agree with you that it can be confusing and not the best UX! To improve it, we are planning to redesign the sidebar so that you can see most (if not all) of the issue's information, removing the need to open the issue in a new window. You can track the discussion and designs in this epic: https://gitlab.com/groups/gitlab-org/-/epics/383#note_108940... Feel free to participate and share your thoughts.
I'd love to hear more about your painpoints with issue boards (and issues in general).
