Similar looking UI to hastags with a small comment symbol instead of hashtags:
Comments must show when hovered over, and should be just as easy to edit something into one.
When a task is marked as done, logseq can be configured to automatically delete the comment on it. This will make comments easily viewable while minimally cluttering the outline of task.
Much better than current implementation especially if finding a comment lost in a large list of tasks. It will also improve use for longform writing. We can call this as ‘notes’ instead if the old comment system has to stay.
PS Auto-delete feature in general is also very useful if a list of tasks can be specified to automatically delete done tasks.
