I can support making the mobile topic list date very suppressed, e.g. constant very light grey. @zogstrip can you turn off the age color mapping on last post dates (for mobile), and switch to a constant very suppressed grey color – let’s use the light/dark functions so it works right on dark bg sites as well.
Also as @simon noted tapping the avatar should jump to the topic in this case.
Other than those two changes I think we should ship this as default.
