Hourly temperatures in horizontal scroll
Expand the current days temperature to be in hourly blocks rather than summarised over 3 hour intervals. It could even be included in the settings as a more detailed option for those that might prefer it
Unfortunately getting data this accurate is tricky, typically when you see this feature they may be using tricks like interpolation (averaging) between two 3 hour data points. I have been looking for a data source that can give this but it get both expensive and technical to implement.
