It would be nice to be able to set the minimum ALT shown in the Planning Tools, as well as add a line at a specific ALT.
I use Planning Tools to help determine the start and stop times based on altitude (30 degrees in my case), so I really don’t care to see down to -80. If I could set the minimum to, for example, 0 degrees and display a second line at 30 degrees, it would help me know when to start and stop.
