Mapper: Enhancement: Temporary highlight GPS Position

[mlerjen]

Steps to reproduce

1. Working with a pretty good external GPS, the symbol representing the actual position gets highly unremarkable, especially over heavy background templates or scribbled areas.

Actual behaviour

fig.1. not best example but it gets close to invisible on the red or brown areas

Expected behaviour

I seek an opiton to temporarily highlight the GPS Position by using a more prominent symbology for a short while (3 seconds) before returning to the normal symbology. Highlight might be somehow triggered for example by switching on and off GPS positioning.

Configuration

Mapper Version: 0.8.2.
Operating System: Android

Doesn't Move to location button help here? It always adjusts map view so that actual position is in the center.

For me better solution is to add customization of GPS position and GPS track. Record temporary trace is not recording track on my Note 4 when screen is off. Thus I usually rely on very tiny system GPS track (this is one is really hard to see).

@lpechacek Move to location does not help much if the background is more prominent than the GPSmark.
@krticka I think it is generally okay that the GPS mark is plain, I just would appreciate the possibility to highlight the information for instance. Of course this could also be applied to the recorded track.

Relates to #986.

Might be more interesting to allow user to customize the diameter of the outer red circle, which shows the precision of GNSS signal. Now it's hard set to 66,66 %, if I am not mistaken, so presenting a slider in the settings of Android which would allow a user to change it to other (higher) value, it should make it more useful and also better visible in the devices with very precise GPS.

How about combining highlighting with the "move to location" function? I would love that.

While we're in here, I would like to see the gray distance circles get a thicker line width.

I wonder if some sort of (slow) animation, such as blinking or spinning highlight, would be useful (and justify increased power consumption).

For the record:

Current diameter of the red dot is 1 mm on screen:

Curreent line width of the red accuracy circle is 0.2 mm on screen:

Current line width is 0.1 mm on screen:

Activating the compass should change the red dot into an red arrow of app. 2 mm length, but this is broken, and it wouldn't be much more visible in the given example. (Will fix it anyway.)
