i could just perhaps make a mod, dont think everyone would want this but i could again make a mod for those that do want it. just upload the files and ill make a mod for you.
Here are the transparent files. I can include the extended one, but the problem with that is...if you make extended transparent, the nofication background slides in front of it when you pull down....so you have to make it black or leave it stock smoke so that the pulldown background appears to slide under it when you are pulling the notifications up and down.
Also, remember that if those who chose to go transparent, and use a wallpaper that is bright...or white...then the signal, battery, time, etc will not be visible. Looks great with dark backgrounds though.
Names of the files should be correct. I would mod the framework myself to update appearance, but...theme manager makes this pretty much unnecessary. (except for the battery icons...etc, which WOULD require modding the framework-res.apk). I would make one optimized for the Droid1 framework, if interested, but it would take me a while. May be worthwhile now as updates have slowed down. Hopefully the devs at MIUI dont change theming too much.
