I mentioned this is passing in another thread, but will make it an official request in this thread, since it looks like it wasn't picked up in v9.4.3b.
I request that METAR and Terrain Opacities persist once set by the User, like Wx opacity already does.
Is there a reason that these opacities must always reset to an iFly default on startup? Terrain is not dark enough for my tablet (and I rely on terrain a lot out here in the mountains) and even TFR's don't paint as dark as I would like at the default 30%.
(As an aside, as the number of persistent user settings grow, it might be that a "Reset all settings to Default" will be needed someday to reset all User settings to a baseline configuration, as is an option in my video editing program.)
