I’d normally leave the font effects in (to make it more consistent with CI4 and CI5, which do have those effects even on the medium font), however I don’t think it looks particularly nice, so… Fixed in v.140.4
Bug
Mmm… no
Changed in v.140.4
Idea
The current plan is: Stand-alone Seasons will use the original HUDs (and GUI, more generally), but I don’t think this feature will ever make it into CIU.
