Like others, I believe that your problem is with markdown and not Obsidian. I really recommend learning it, though, as it will give you the ability to have your plain text structured (and subsequently formatted) in a huge variety of apps and platforms. For me at least, there was no going back.
There are a ton of online guides (like Markdown Guide) and online markdown editors (like Dillinger).
As for Obsidian’s editor, there’s still room for improvement. A very popular feature request is a WYSIWYM (Typora-like) editing mode, and that will probably make it easier for people with little or no knowledge of markdown to deal with its syntax.
I second Scotty’s offer
It might be interesting to see how different people would go about it.
