If you've been using the Google+ Android app for any amount of time, then you've probably noticed one thing: there's a lot of white. The majority of the screen - especially on a tablet - is blanketed in with a white backdrop consistently throughout the app. This is, of course, hard on the eyes (especially in a dark room), and can negatively impact battery life on phones with AMOLED displays.
To the rescue comes XDA forum member santiemanuel, offering his own themed mod of the G+ app, simply called Krad+. It's offers a completely inverted theme, and it looks damn good doing it. Take a look:
Of course, the one downfall of using this modified G+ app is the fact that it will not receive Market updates, so you'll have to keep an eye on the source thread to grab the latest version.
It's also worth noting that you must remove the stock version of the app before you install this one.
You can grab the app from this thread over at XDA.
