Thanks for the feedback!
Still a few things to clean up, and I posted a list of some of the things I hope are coming soon...
@deantemple-
I have a few more themes to post up, but the next big item to tackle is being able to automate cracking open services.jar, editing, and putting it back together... Once that's working, then I believe the ability to include themed apps is next. The challange there, is that every ROM has a different settings.apk, phone.apk, etc. So if those are themed, I'll have to automate stripping the themed components from that app, and themeing the app that's included with the ROM... either that, or I need to find a way to show a theme as compatible/not-compatible with a particular ROM.. It's a pretty big task, we'll see how it goes along the way...
I'd like to put it into an app, but have done almost nothing with java.. honestly, most of the back-end script will run on the phone with a few minor tweaks..

If someone wanted to work with me on an app, I'd definitely be interested.
@Plower.net-
I'd like to do the larger preview.. right now, the site works really well on the phone.. and I definitely don't want to spoil that! On the other hand, the site could use some cosmetic changes. Unfortunately, I'm horribly horribly weak in php/js. My website coding -fu is terribly weak... Would DEF. love if someone was interested in doing more on the web...
What I'd like to do (my end goal, kinda).. is have a mock image or two off to the side, and as components are chosen, the image updates with them to show what the theme would look like with the chosen components...
It's a lofty goal, but if someone who was better with php/js/whatever would be required to do something like this wants to get involved.. I'm all for it!
As far as apps, as I mentioned previously, it should be included shortly. Funny that the apps you mentioned if included in a theme by the theme developer.. would be about 4 lines of code in my script to include those apps... It's things like phone/dialer, settings.apk, etc. that will break stuff from one ROM to another that I have to work with a little to allow inclusion of themed apps with themes.
Uhmm, soon. I .. hope.
@Droid74-
You do the hard stuff, I just put them up and let you test...
@Corinacakes-
Yea, I made it a little more obvious as to where the links are.
@chkm8-
It's on my list to PM you, to see if you might be interested in having some of those boot animations hosted... heh. Might be a while, lot of stuff on the list before that, but if you're interested, let me know!
@themers-
If interested in having theme hosted on the site, let me know... It's not hard to do, and the only real limitation currently is the apps.. but hopefully soon that'll be working.
And thanks to all for the feedback.

I'm excited about the possibilities as well!
