Display long headers and icons on the right side of the screen

I want my long note title headings to be fully displayed in Obsidian. Most of my notes have long titles, but I have to shorten them considerably so that Obsidian doesn’t cut them off.

I found online what it looks like from one of the users. I want to understand how it is possible to do the same.

Also, I’d be interested in how to make the note icons display on the right instead of the left (using a plugin)
