Hi, the Isobars are great :)
To make greater still it would be very nice to have the option to show at intervals of 4 hPa as this is the commonly used spacing on many (most?). synoptic charts so is what users are most familiar with. With the current 2hPa spacing the charts can look pretty alarming when your brain is dialled in for wider spacing!
Could this preference be incorporated as a toggle into the settings section?
Many thanks for a great ap!
