Blog page from notes (by tags, dates, and other params)

Hi. I so love your service, thank you so much for your efforts )))

Please, do a regular blog page for user notes. I want to have a public page with my posts with:

- title,
- image,
- description

Or even better -- blog page by user tags, dates.

For example, my username is user1, and I wrote 10 posts with tags "project-1" and "completed", and I want to share them all by one link:
`hackmd.io?user=user1&tags=[project1, completed]`
It will be so cool.

I know about your feature "Book", but it is annoying to write its content manually every time when something had changed.

Please add this feature... :fox_face:
