[nclpy-group] Thoughts on changing NCL's default map database to "MediumRes"

Perhaps as an interim solution, we can offer up a new logical resource that tells NCL to crop the map based on the lat/lon values provided by the user, so at least you only have one resource to set instead of four. 


I also find this annoying but rather than change the default or existing features. 
Could you add another option to mpLimitMode as “Data” which sets the limits to the data extents. 
Makes it a quick thing to type out without having to manually set the extents and doesn’t (shouldn’t) break anything existing. 


3)  Similar to this discussion, is there any feasibility to have a “defaults” file where the user could change some of these options?  
I have tons of repeat resources in every script, which just change font sizes etc and I pretty much always change them to the same value. 
I personally also will willingly take the time hit to have nice coastlines.  Globally these things probably shouldn’t be changed, but if the user could set their own defaults it could be quite nice. 

Actually this is kind of done with the set_default_fillvalue().  
Could we have e.g.  
set_default_resource(“txFontHeightF”, 0.018)  
A file with these could then be loaded at the top of scripts without having to think too much about it.
