This is a plugin that provides a query language which allows me to do a few things I had on my wishlist. For instance using the Day log note to also show notes created on that day. Dataviews works by using the ability of Obsidian to insert code into a note.
I added the following at the end of my Day log note for today:
TABLE file.ctime as Created, file.size, file.path as Path
WHERE date(2021-03-15T23:59:59) - file.ctime <= dur(1 days) SORT file.ctime desc ```
Which results in a list of files created on March 15th.
I added this to the Alfred snippet I use as a template for my Day logs, so that it will have the right date. I use fixed dates because then it will always be a record of notes created that day, also when I look back to a day log in a month or week etc.
[UPDATE 2021/03/20] In a conversation on the Dutch Obsidian Discord channel, Frank notes that my query above als retrieves any notes created after the date in question, because then the evaluated value becomes negative, which is also smaller than 1 days. I hadn't noticed as I hadn't looked back yet to an earlier day note. So it needs, as Maarten suggested, an additional statement to exclude those negative values, along the lines of
and date(2021-03-15T23:59:59) - file.ctime >= dur(0 days)
