A nice feature, for me and maybe others, would be to automatically select the altitude for weather related item that change with Altitude. For example, I set up a flight plan using Simbrief. Simbrief provides suggested altitude for the aircraft and flight plan. I then load the flight plan in Navigraph Charts.
I have three options selected in Weather i.e. Wind Barbs, SIGWX and Weather. Some of the options (wind barbs) can be adjusted by altitude.
The ASK is to set the default altitude, altitude for which first appears when I select the Weather button, based on my flight plan. Right now, the default altitude is FL220.
You can get the default altitude from Options (image below). The first time I select the Weather button the default altitude would be my flight plan altitude.
