Note on inverted and otherwise modded apps
I completely understand everyones wanted to 'black out' the market and other apps. All I can say if you have a problem is revert back to the one that came with the ROM. That will fix your problem, but before doing so, uninstall the app or remove from /system/app, then reboot into recovery wipe cache, and davlik cache, then reinstall the ROM and Google apps, and the optional apps if you wish. That will fix it and put you back to normal.
The problem with inverted apps are the many that are out there aren't the newest ones or they may have been added to. So to fix this JayR83 has opted to manually update them for you, so Thanks JayR83 for that. For now I would send him links to the app you want ported to DC and my guess is he'll do it for you.
Porting an app is a pain and time consuming, you have to pull the res folder on both apps and compare the images from the newest stock version to the sometimes old/moded themed version. If theres an image in the stock version that is missing in the themed it will give you problems, or if there are extra images in the themed version you can get problems sometimes too. So basically its time consuming to compare and make sure that all the images in the theme match the stock. Then its a matter of taking the good themed images and putting them over the stock ones. So please be patient with him, its very nice of him to offer. So thanks JayR83
