I have lots of needs in terms of journal practices 
.. these are some of the few.
For Productivity Evaluation
I would like to see everything I have done on the date of journal.
- Automation to making set queryâs filter which match journal date and object creation date, as well as modified objects - information can be pulled from version history.
- All checkbox text block across objects (not task object) can have date relations for creation and completion.
- Formula or calculation and list of total started / completed task
- Words / letters input counts for all work done on Anytype for that journal date
For Contemplation and Reflection
I would need better flow and relations to have smooth process.
- Handwriting - just let everything in mind flow
- Thought flow: Feeling objects relating to event / thought objects, specify to journal date - enabling pattern observations, e.g. frustration to hanging projects across different dates / time, thus accumulated effects; but also happiness to seeing sunshine in the morning (Not just a single mood for the whole day)
For Relay / Quick notes / Referencing
I would want capture insights everywhere and easily organise them for later use, while maintain links to journal object. Like an inbox.
Accessibility of journaling object, so I can reach it no matter what main object I am using. E.g. pane between sidebar and object or tabs to display multiple object alongside journal object.
P.S. I have never found an app which satisfy my journaling needs, so there are possibly more needs I am not aware of. Hope Anytype will be the one I go to
