First I just wanted to say that I am very much loving Live Preview and Obsidian in general. It has helped my life in many many ways!
Anyways, this is mainly cosmetic, but oftentimes I will add backslashes before
#, and other special markdown characters when I want to use their literal versions.
Now that we are blessed with the Live Preview Mode, it would be cool for there to be a setting to enable or disable the visibility of these backslashes since we always have the option to go into Source Mode to see them, not to mention simply toggling this proposed setting off.
I will usually just toggle Preview Mode on temporarily. I do this mainly because sometimes the backslashes interfere visually with double checking that everything was done correctly.
