First Question = No.
Those stay until the next update unfortunately.
But perhaps you’d like to start a Wish List item for this, if there isn’t one already?
Not every wish list will ever be implemented ( can’t please everybody ).
Second question= Everyone’s annoyance’s are different and again, maybe a wish list item to start off.
But also note that info is available:
Every update has a link to Release Notes as the update is running, lower right side during install.
Every update has Release Notes posted and retained News & Annoucements .
The bottom left on msfs main page under Release Notes (most recent only).
Also Home Page, Twitch, YouTube, FAQ / Zendesk, Discord, Facebook, Twitter etc.
