Never tried myself, but it seems you can do something in the menu Customize -> ArcMap Options.
Here you'll find a Data View page where you can set the fonts for the labels.
A similar option is also present fot the Tables page.
This won't basically change your fonts "application-wise", but for labels and tables only.
The answer to the question "Can this be effectively fixed?" is essentially no. The picture below illustrates why it is a good thing that the outer pink boundary is created by the topology and displayed and why only the user can determine if the exterior boundary shown contains an error or is as correct as it will ever be and is a topological exception.
When the rhino track is already in the dictionary you need to pull out its array before trying to update. Also don't add the array to the dictionary as a list.
if name in rhino_dict:
sighting = arcpy.Point(lon,lat)
rhino_track = rhino_dict [name] #### get correct track
#rhino_dict[name] = [rhino_track] ###adding as ...

A group layer contains other layers. Group layers help organize
related kinds of layers in a map and can be used to define advanced
A group layer behaves similarly to other layers in the table of

This 'black border' is probably 'background value' (normally RGB: 0,0,0). You can check the value of this 'black border' by using the Identify tool and clicking on it.
If I understood correctly, you need to remove or mask this background first before doing your mosaic layer by for example 'Mosaic to New Raster'.
One option, (if it is just about not seeing ...
Assuming all the times are from the same day, you can calculate the delta between the start time and the end time using the following Python function:
def delta(start, end):
start_dt = datetime.datetime.strptime(start, '%H%M')
end_dt = datetime.datetime.strptime(end, '%H%M')
return (end_dt - start_dt).seconds / 60
This function ...
I just had to do this myself. I followed another post as guidance How to extend raster data for larger boundary?
What you're looking for is a Euclidean Allocation.
Make sure you specify the shapefile boundary in the processing extent.
