RueI is a hint framework, designed to be the definitive way to display multiple hints at once. you can get the latest release here.
docs are available here.
if you want to develop using RueI, make sure you install the nuget package
RueI is not a grid-based or line-based system, it calculates the offset necessary to put a hint at the same position no matter what
if you've encountered any bugs please make an issue (it helps me out a ton)
