I didn’t know where to begin, it wasn’t until I started customizing the theme of this blog that I noticed an issue I had encountered before. Have you ever found in order to format a description; you’ll need some knowledge of HTML? This isn’t so much of a problem as it is an annoyance. As a theme designer I get a lot of questions asking to do some very simple things, why isn’t that Tumblr caters to these people in the most basic of places?
I’m not suggesting they add a full blown HTML editor but something like in the second picture would be nice with a system that detected plain text input and output HTML, ie. you hit return and it makes a new paragraph, easy.
