Pressing ‘option + up’ in sidebar will open many windows

When I click on a project in the sidebar(bottom project on project list) and then press ‘option + up’, it opens all the projects to seperate windows from sidebar. Can you explain why this happens?

Are you using Agenda 18.3? This could be an oversight from our end and has to do with an option click resulting in opening the project in a window. We’ll check it out and will fix in the next update if we can reproduce it. Thanks for reporting and apologies for the hassle.
