I have made an MIUI Theme Editor - a PC based tool that allows the user to make, edit and save themes for MIUI!
Its been in BETA for a while, thus the thread already being a bit long, and I believe it is finally stable enough to release publicly. So I have!
I have released the program, and it is available at http://www.miuithe.me/. I still, however, ask you to please send me as many suggestions as you can think of! All suggestions will be taken on board! Suggestions can be made through the Issues and Suggestions page of the above website.
Please note this is a PC application - not an android app... Sorry, but I'm just not that good with java!
Available at MIUI Theme Editor Website.
Full Changelog Available at MIUI Theme Editor Website.
Available to Download at the MIUI Theme Editor Website.
Please submit all bugs and suggestions to the Issues and Suggestions page on the website.
