The Markdown plugin has lost features in between IC-203.7717.56 and IU-221.3427.89
In IDEA 2020 there were icons for Bold, Strikethrough, Italic, Code, Decrease/Increase Header level, Introduce reference.
On the right there were options to view in Editor only, Editor and Preview split, Preview only, Autoscroll preview.
All these have gone in 2022.1 and I am stuck with Editor and Preview split.
Is this a bug or have you deliberately removed functionality?
