It's probably a matter of taste, so it should be an option. I'll definitely add something like that at some point. Next thing on my list right now is finally adding re-steeming, upvoting and then writing posts which is a bit more elaborate, especially since SteemConnect doesn't support it yet (unless they've added that over the last few months, haven't checked again). I want to add lots of features like drafts and a version history with diffs, maybe optionally a WYSIWYG editor that you can use instead of markdown (but which uses markdown behind the scenes so you can switch back and forth between the two).
