Do you want to make sure you always notice posts by particular accounts you are following?
You can switch on notifications for posts from those accounts by going to their profile page and clicking on the 🔔 bell icon.
Clicking the bell means you will get a notification every time that account posts. The notification will appear in the same place you get notified about boosts, replies, mentions etc.
(If you change your mind, just click the bell again to switch it off.)
