Being new to HTC products (previously rooted Moto products), I am unfamiliar with xposed. I need to search out the tutorial on how to use it, cause it appears to be pretty useful.

donwoad and install from there
its pretty simple once you use it a few times, here is a quickie:
download and install xposed
open xposed
choose framework and click install/update
itll ask you to update, choose yes and do the soft reboot
after you rebooted
open xposed
choose downloads and find whatever module you think will come in handy (some are only compatible with certain devices)
download the module and it will say its not activated
back up and go to modules, select it to activate it (you can touch the module to adjust any settings if there are any)
do a soft reboot and the module will start working
