Insight

Insight is a information mod that includes 3d tooltips/widgets/GUI's (what ever you want to call them) to the game with multiple features:

TargetHUD (With an option for smart positioning, which dynamically positions the HUD for optimal visibility based on your view angle)

TargetHUD helps with entity information, specifically health

Dropped Items

Dropped Items is useful in cases where you dont know what the block is on the ground (maybe a modpack, or a vanilla item that is dark or unrecognizable), its faster than picking it up

Bed Timer

Bed Timer helps you know when night time comes

And more, insight comes with customization, via config tab

if you are on Fabric i highly recommend Mod Menu to configure Insight

Insight comes in multiple mod loaders, and (soon) multiple Minecraft versions for universal access

Insight is still in early beta, expect some bugs!
