PotionEffects

PotionEffects
PotionEffects replaces the default Minecraft status effect display with a cleaner, more informative HUD designed to keep you aware of your active effects at a glance.
Features

Clean icon boxes displayed on the left side of your screen, vertically centred
Timer displayed directly on the icon so you always know how long an effect lasts
Roman numerals on the icon for effects above level I, just like vanilla but better integrated
Low-time warning: the border, timer, and numerals all flash red when an effect is about to expire
Infinite effects show a ∞ symbol instead of a countdown
Replaces the vanilla effect display entirely for a distraction-free experience

Customisation
Open the settings screen at any time with the configurable keybind (default: K) to adjust:

Opacity — control how transparent the entire HUD is
Timer position — show the timer inside the icon box or to the right of it
Roman numerals — toggle effect level numerals on or off
Flash warning time — set how many seconds before expiry the flashing starts, or set it to 0 to disable flashing entirely

Settings are saved automatically and persist across sessions.
