Automatic DTED download should be an option

Issue

Automatic DTED download is using a lot of bandwidth without warning. Unlike map layers, the user has no control over this other than DNS blocking tak.gov.

Recommendation

Make automatic DTED downloading a user preference to avoid wasting bandwidth or mobile data.

Some transparency re this feature would be welcome too. The biggest gripe on app store reviews is privacy yet the app is making requests to a .gov domain when a user pans the map - but this isn't mentioned AFAIK.

It is an option and can be disabled as part of settings or you can point to your own private elevation source.
