Feature request: Record a single trackpoint

[m-fessler]

Hello,

first of all, thank you for the great app!

If you allow me a few ideas or suggestions: An option to log directly to a microSD card would be practical, as it would reduce write access to the internal memory.

It would be nice, if there was a "single point mode" where a track would only be created using individual manually created points. Or is this not possible for similar reasons such as an update interval longer than 3s (in order to return a good accuracy)?

It would be great, if there was a filter option where some could specify that track points with an accuracy greater than x meters would be discarded.

Thanks and greetings, Martin
