HoverTTS 1.7 now includes a new section called Extras!

Extras (optional, off by default except the master switch)

Optional UI tools in HoverTTS settings. They do not change speech. Gear Suggestions and Guides are still beta.

Enable Extra Features
Master switch for Gear Suggestions and Guides. Turning it off pauses those two; turning it back on restores your previous settings.

Class Color Unit Health Bars

Player and target health bars use class color. NPC targets stay the default color.

Hide Health Bars on Player Nameplates

With nameplates on (Shift+V), player plates show the name only. NPC plates are unchanged.

Tooltip Scale

Resize item, spell, unit, and comparison tooltips. Default is 1.0.

Aura Bars

ElvUI-style countdown bars on the player and target frames. Bars shrink with time left; timers show as minutes:seconds (3:00, 0:45). Soonest to expire is on top. Seals and other no-timer auras still show. Stances, paladin auras (Devotion, etc.), and tracking (Find Minerals) are hidden. Your curses, judgements, and other player-applied debuffs show on the target. Buffs and most bars use your class color (warlock purple, paladin pink). Curses, poisons, diseases, and magic are green.

Place bars above or below the unit frames

Hide the small buff/debuff icons on the player and target frames (the buffs at the top of the screen stay)

Quest Icons on Nameplates

Questie’s sword (kill) and bag (loot) on enemy nameplates for mobs on your quest log. Questie does not need to be enabled.

I am continuing to work on the Gear Suggestions and Guides portions of this addon.
