I keep notes for various projects. Right now I keep them in one giant diary, which is cumbersome.
If there is enough interest, it would be nice to have a way to keep a separate diary for each activity, but the entries in it would also be added to a master diary.
In the dependent diaries, I would start off each post with a date field and an optional time field; then the note. In the master diary, the same, but then the ability to specify one or more dependent diaries.
When I’m looking at my work with the local library, I have a diary for that, I can read through it for review.
But when I’m trying to find some person or event, and I can’t remember which dependent diary it’s in, or when I wish to review a time period to see what was going on then, or what I was doing, then I can look at the master diary.
