Some notes can be quite a long write (see №2), and they simply won’t be written just at once, in one sit.
That itself is ok, but causes concurrent posts creation to happen.

A minor second thought - seems like aggregating next ideas or themes to write about, possible optimization to the process - is a good thing to do.
Quite a few already saved, waiting for it’s time
