That's almost what I do with my work journal too. Daily logs with an index. A page for deferred tasks. A page here or there for tracking things that need to be done for a given project. I find the index helpful even if I only occasionally put an entry there.

For my personal journal daily logs are the core feature for sure. But I also get a lot of value from a future log, and a page for the current month with a list of events, and scheduled tasks.
