There is a trick for creating horizontal dividing lines in HM2:
1) Go to Config properties> Enable "Show abbreviations"
2) Go to Stat appearance and delete abbrevations from all stats so they dont show up
3) Go to Displayed stats and add any stat(stat you dont need) in place where you want horizontal line
4) Add "New line" above/bellow this stat
5) Go to Stat Appearance and change stat you added to color black, font size 1 (so you will not see green "-")
6) Add abrevation to new stat "________________" (add as many _ as you need to fill the line)
7) Add minsample for this stat to "999999" so number will never show up, only - that we colored black.
