It adds a menu that puts h1, h2 and so on, right at your fingertips. It includes a couple of nice little undo/redo buttons. It looks like this:

It does not much else, yet. My mad skilz are about as pathetic as the phrase “mad skilz” sounds. But I figure my minor annoyance with Tumblr’s limited editing functionality can be your less-minor annoyance. To install this, add Greasemonkey or Tampermonkey to your browser, or as some might call it, your rig.

lefarce asks: Since at least one of you guys have an iPad, what's the best Tumblr app? I'd like an alternative to the browser but it appears that nothing is as good (i.e. Tumbleroo treating posts like the iPad mail client.)
» We say: We admit to not having tried them out yet since they all cost money and all sound not very good. Which is too bad, because the Web interface is hobbled by the iPad’s lack of support for TinyMCE, which is also the same reason that the WordPress app kinda sucks.
Question for you tech-minded Tumblr freaks out there: Is it possible to create a custom-modified version of Tumblr’s TinyMCE/WYSIWYG functionality using a Chrome extension or a Greasemonkey script? We’re thinking of ways to make it easier to post our more-complicated post styles using Tumblr alone, without having to type in lots of HTML. And since the Tumblr API is relatively unreliable (and also because it’d be a lot more work, since we’re not professional programmers and we’d have to figure out what we were doing), it’d be easier to modify TinyMCE to use a custom CSS file and a series of post templates. Certain Chrome extensions get partway there, but not all the way. Above is a screenshot of our WordPress setup, which we hacked to do the above. We’d like to do something similar without using WordPress at all. (Sorry for the nerdery … we’ll get back to making fun of Sarah Palin Joe Miller with the next post, we swear.)
