It took me pretty long to find the new option “shrink images” in the 2.1.55 editor (even with add-ons disabled. My problem was not that the new icon was buried in the mass of add-on symbols).
I’d would have been much easier if I had some pop-up message the first time I opened the editor in the latest Anki version.
I don’t advocate for such messages for every small change in Anki. Only stuff that can totally change or ruin your Anki experience like the introduction of the note-card toggle in the browser or the “toggle sticky” symbol in the editor.
