I have been using Gravitybox for L navigation bar, data traffic monitor, quick settings quick pull down and swipe to notifications, signal bar and battery, pie controls and auto expand volume panel. Maybe more. Xblast tools for power menu, notification panel tweaks, lock screen, text and spinner colors, toast and popup colors, + more. Xuimod for scrolling, listview and toast animations. Complete Action Plus. Xhalo floating window. Screen filter to dim screen at night more than what it normally will, and to put all these settings in one easy to find place, Xposed Preference Injector to put the apps with a ui in settings list. I do not get force closes as long as its set up right. You can't have more than one module modifying the same exact thing. You can have both Gravitybox and Xblast change something in the status bar for instance, but they can't both be set to change the same thing in the status bar. If you try them both, don't be surprised by the 2 clocks and 2 batteries, you just have to turn one off on one module or the other. I have nearly every mod available on custom ROMs. You just have to play around with them a bit. This phone seems to tolerate Xposed mods a lot better than previous phones I've had.
