Default Quickmemo stopped working

I was unable to Launch my Quickmemo. I'm on stock kitkat rom, rooted. Anyone who can help? What are the processes/apps that control Quickmemo? Maybe I accidentally deleted/greenified/modified some essential system apps.

Also, the following were the things I'm playing with in the past days:

1. Latest Dorimanx kernel
2. Xposed framework with the following modules: app settings, gravity box (kk) and greenify

Maybe uninstalling some of them may work. Thanks.
