So, it's a glorified timer, right? What advantages does this have over the native timer app?

It looks intentional, not a screwup. This is a new version, like the difference between CS5 and CS6. You get an option to migrate presets and plugins when you first open the new version.

Looks like this is the new naming schema.

Adobe CS Adobe CS2 Adobe CS3 Adobe CS4 Adobe CS5 Adobe CS5.5 Adobe CS6 Adobe CC Adobe CC (2014) Adobe CC (2015) etc…

The surprising thing here is that you'll need to uninstall the CC version as the CC (2014) is a seperate app and install. I was (falsely) under the impression that the live update model would do away with this.

Yeah, this was shown at the WWDC keynote :)

Is there syntax highlighting available for Tumblr's custom layout language, in say… Sublime Text?

1. looks like the the elements are flying in from off the stage, causing the right side white space. Simply add overflow-x: hidden; to the body and it'll be fixed.

2. Don't fully understand you're question here, but "margin-x:" is not a thing. Try "margin-right:" and "margin-left:"

Well, when you compare it to the $150 upgrade price of Photoshop…

Now if only my.cl.ly would get an update!

No, it does not… http://tiny.ec/image/2f0M0T1R3O3r

Apple understands that white space is important; as is not having more than 3 product columns at any time, and making the product photo front and center, not some cutesy font.
