Much like the timestamps, this can be done using invisible text.

if nobody else does, i might try tackling this after #173 / #182

[kimlimjustin]

@JackDotJS have you started working on this? I've figured out a way to handle this, what left is just to open a PR

[JackDotJS]

nope, i'm still waiting for approval on the other PR x) feel free to take this one!

[JackDotJS]

seeing as #188 kinda fell apart a while back, i figured i'd try sorting this out myself x)
