Frankly, you can imitate the experience of Logseq in Dendron by simply writing everything into your daily notes (equivalent to journal in Logseq), instead of putting in separate hierarchy. Then you can categorize the daily journal with hierarchical tags in Dendron (similar to namespace concept in Logseq). When you find a good reason, you will create a dedicated hierarchy structure for new notes (similar to creating a page in Logseq)
