○ Displays number of targets hit and totals for AoE cures/damage.
○ Displays casting, completed, and interrupted icons.

Self Actions.

○ Displays a casting bar based on casting time for spells and items.
Party Actions.
○ A simplified display of the actions performed by each party/alliance member.

Display Debuffs on Monsters.
○ Shows the tiers of the debuffs (Frazzle 3, Slow 2, etc.)
○ Will show a best guess timer for each.
○ Removes the icon only when the debuff is known to be removed/off (ie Benediction or "wears off" message), otherwise displays "??" if unsure.
Display Monster levels.
Display the Index or Hex number for targets.
○ Useful for NM placeholder camping, or designating a specific mob for others to target.
Display distance to target.
○ Colorize the distance text based on the distance to the target and other factors.
Displays SP abilities and time remaining.
○ Accounts for an SP ability being stolen with Larceny.
○ NOTE: Timing for players who have gear adding additional time cannot be accounted for.

Animations!
○ Bar Fade - fades away after a set time of inactivity.
○ Bar Pulse - pulses the bar under certain circumstance (SP ability active, TP is ready, critical HP, etc.).
○ Bar Drain - bar meter updates immediately, while the newly "missing" part of the bar smoothly drains away.
Player Stats (HP/MP/TP/Pet) can be turned on/off individually per job (ie SAM could show only TP, while PLD shows HP, MP, and TP).
Names and bars colored based on type (NPC, Party member, mob claimed by someone else, etc.).
Nearly every feature can be turned on/off or adjusted via settings file or in-game commands.
See github readme for full list of in-game commands and settings file options.
I originally built Bars to address some shortcomings of another bar that showed enemies, then ended up fleshing it out with other things I thought would be cool to have. I really enjoyed working on this one and am super happy with how it turned out. I made sure there are lots of adjustability options if you want to change how it works. You can turn off almost everything about it to make it a very simple target bar, but I think you'll like some of the extras packed in :)
