Other seemingly more minor (but which will possibly be more widely used eventually) features are different forms of underline, selectable through sub-parameters to SGR 4. I've already put this into my terminal emulator, although that version is not released yet; it exists in LibVTE and several other terminal emulators; and the Windows Terminal people also have a backlog item for it. * https://github.com/microsoft/terminal/issues/7228 https://github.com/microsoft/terminal/issues/7228
