At a Project/List level, it would be powerful to be able to have tags, extend the metadata, and allow for reporting.
Some context -> We use Lists to organise our projects, rather than the ClickUp Project primitive, mainly because we have a lot of projects (but the same ask here would apply if we used Project for our projects). As a manager overseeing many projects across many applications and functions, it has proved tricky to provide an overview at a more coarse level than tasks. In particular, I would like to understand and socialise to the rest of the management team the in-flight and completed projects and perhaps some detail on their status and number of outstanding tasks. The workaround has been to place a project_tracker task (tagged as project_tracker and sharing the name of the list) within the list, apply a status to this project_tracker task, and then filter for these tasks at the Team level. Closed projects (lists we've archived) are a bit more tricky to follow. In any case, having the ability to place tags and fill out metadata (status, start_date, end_date, etc.) would certainly make my life a little better.
