In health overlay you had a config option for displaying the health numerically. Any Chance of that coming back?
"display_mode": "OFF",
/* Text displayed next to health. Minecraft chat color codes are allowed.
Available variables:
"[HEALTH]": Current health.
"[MAX]": Max health.
"[HEARTS]": Current health in hearts.
"[MAX_HEARTS]": Max health in hearts.
"[ROW]": Current health row.
"[MAX_ROW]": Max health row.

Unfortunately no. I have decided to not add any more extra features than needed into colorful hearts. I did just add support for overflowing bars' row counter that should give similar behaviour in #20 . Just make sure to disable allowLayers for hearts in overflowing bars' config file.
