Uses the same folder-list paradigm as ClickUp, which, as a long time JIRA user recently converted to ClickUp, I find to be a plus. The simplicity and responsiveness of the interface appears to be an improvement over ClickUp. However, one thing I love about ClickUp is its ability to quickly configure task statuses (which in JIRA, is the equivalent of programming a VCR). So if this product could add flexible task statuses, and also task tags, it might be a low cost contender to ClickUp.

Edit: also, rather than folders > lists > sections, it might be worthwhile to introduce nested folders, which is a very popular feature request in ClickUp but that team never actually got around to adding it. Another thing: subtasks.
