That said would be cool if pressure lines (or even wind animation) were available on observations layers. Could infer where the rain areas are moving and why.
I use windy mostly for the radar. Love all the other stuff but the radar is what usually brings me into the app. Now I usually just sweep back and forth on the slider and let my brain extrapolate from that what's going to happen within the next hour or so. Works very well for avoiding getting wet :-)
But then sometimes to better understand what's happening I do go back and forth between the radar, wind, and satellite layers. The animation takes a while to pick up and the pressure lines give a faster and more overall picture so would be cool not to have to hunt for the toggle every time
