I think it would be a nice feature, maybe even a tag? <lineSize>.
I guess I can just math it out myself though, a <lineSpacing=-1> should kinda do the same as if I made the line height 8, instead of 9.
It seems I never run out of questions (though I am heading to bed in 5 minutes over here.):
Is there a way I can set the width of "space"? In TextMeshPro I think this used to be in the Font Asset. I already thought of a workaround using the tab instead of space, (I won't use tab anyways) I just wanted to ask. For some reason some of the pixel fonts I use seem to have a massive space size. I assume it's set by the font and you can't really override it.
