[Feature Request] Import starred items

[timothevs]

I would like to request a way to import starred entries into the system, OR if there is already a way to accomplish this, I'd like to request some documentation regarding the same.

I'm a fan of how minimal Miniflux is, but like others, I am moving to this app after nearly a decade with other apps (GReader, TTRSS, Feedbin, etc).

A simple way of importing starred entries, would be awesome.

#329 seems to overlap with this.
