It seems all of xposed modules run at the same time now.
This make the messy result sometimes when using the modules which hooks same things.
For example, I'm changing the size and format of clock on the statusbar with module A and I'm using module B also to theme my rom and this contains the function changing the size of clock on the statusbar also.
As you see, it seems that A and B have same function. But their way to make it in technical are not same.
This makes the size of clock every boot different, and users and devs can't set the module which hooks something LAST.
I asked @rovo89 before about the 'priority' of modules before and he answered xposed framework doesn't.
But I recognized my question was wrong recently.
I had to ask the 'batch' of modules :P
I think making a batch could solve the concurrent hooks
