I've been working on the Material Design / "Android Theme" for Syiro. It is coming along well. I implemented most of the Navbar Component styling, Button and Toggle Button styling, and most of the List / List Item styling.
As a result, as I'm sure you can imagine, a good chunk of LESS has been refactored. Oddly enough, I borked some of the Buttongroup styling along the way, but some hiccups were expected. Player styling has been moved to core-theme, as has the Searchbox Component styling (I haven't decided yet whether or not the Searchbox styling should remain intact, since the Material Design Searchbox styling is outright mediocre at best.
Animations are partially derped, namely the toggle animations, since they were set to a fixed width. Nothing a simple refactoring can't fix.
I haven't tackled the "special" animations that Polymer implements. I probably won't implement the majority of them either, seems like a good chunk is WebKit specific (and by WebKit I actually mean
webkit). But some of the button focusing and toggle button focusing *should
land in 1.3.
Player styling will get a slight
makeover for Material Design. I want it to feel at home but maintain Syiro's styling to an extent.
Toggle Button in default-theme will get a makeover as well. After looking at Material Design's Toggle Button design I'm mainly thinking "damn, default-theme's needs a makeover.", so that'll land in 1.3
