Feature requests for use as a vehicle dashcam

[stallmandidnothingwrong]

I love your application it's the only usable free software as a dashcam for my vehicle. I have a few feature requests to make it better for this purpose. In order from being most need to least needed (in my opinion):

1. Tap to save last (x) batches without interupting recording with a single input from the user:

The amount of batches should ideally be different than from the normal setting so it can be saved quickly. If this option is enabled by the user it should be a large yellow button above "enable torch". This should require a single tap and the save location should be configured in the settings before use (user home directory by default). The recording should not be interrupted so the user can tap the button again if needed. If button is tapped successfully there should be some audible feedback in case user is crippled and can't see too well.

2. Option to save last (x) batches without interrupting recording if high change in motion is detected

Similar to above option except instead of user tapping a button the app will automatically save last (x) batches if extreme change in motion is detected by motion sensor. Instead of a low, medium, and high sensitivity option as found in properietary dashcams, it should be a configurable integer by the user with 0 (feature disabled), 1-3 (low, saves easily), 4-6 (medium), and 7-9 (high, requires extreme change in motion to save). If a recording is saved by this feature, audible feedback should be given so the user can configure the sensitivity easily.

3. Option to overlay video with time.

4. Change targeted bitrate from using megabyte to megabit, because that's what all other recording devices I have seen use. Some users may not be aware of the difference between MB and Mb and end up recording obsenely large files.

5. Option to overlay video with gps coordinates.
