For info I do not have any notes at all where the note title is repeated as the first line of the note itself. I never considered doing that because I have always considered it duplication. That's what having a note title field is for.

I thought that at first but there is limited space in those locations especially the edit-bar when using the edit pane. Just a couple of tags could easily fill all the available space.

The layout for me is fine as it is, I was just suggesting that if the title is made bigger / bolder it should not be made too big, just enough to empasise the title amongst all the other elements of the note's header. I use Joplin almost filling a 24" 1920x1200 screen so it will not impact me at all but there will be people out there using 13" or smaller ultra portables who may have less space to play with. It's a minor point but I was just putting it forward as something to consider.
