A new Meizu user here. I really like the FlymeOS, but noticed a few icons like google drive have an ugly white square background.

I found the icons file that can be used to add new icons. I was wondering if there is a simple way to update an icon, or do i need to search the apk or web for the icon, and then manually add it to the icons zip file?

Another point of interest is the themes. Were do they get saved and can you add them to a local folder manually, or must you always get them from the meizu market?

If they can be easily added (and then loaded with the personalize app), what is the format of a theme, I know it consists of at most 5 modular parts, but what do the files look like.
