The wysiwyg editor is pretty nice, but there are still times when it's frustrating -- part of the whole idea of markdown was that it's easy to type, in a normal plaintext editor.
What is the point of showing the markdown in a readonly view, without letting us modify it?
There are still situations where I have to hit 'Copy' and paste into my favorite text editor, make the one- or two-character formatting change I need, than select-all and copy/paste it back into Trello.
That works -- so obviously trello has code to parse markdown from the clipboard -- why not allow us to modify the markdown, without leaving Trello?
A text-entry experience similar to reddit.com, allowing to seamlessly flip from wysiwyg to markdown, would be helpful.
