In a drawing I would like all my views to have a default of high quality instead of draft quality. Currently our practice is to change it manually for every view, which is very time consuming

I can't access Solidworks right now (our license server is down).  However, there are two things that I can think of off the cuff.

1) I think that You can Shift select all your views in the tree and change it for all views at once.  Maybe....I would have to test it and I think I remember doing something similar.

2) I think that there is a setting:

Cosmetic thread display option in Tools > Options > Document Properties > Detailing

You would have to update your template to make this permanent.

What's the difference between a sheet format and drawing template?

Why aren't the changes I made at Tools > Options > Document Properties saved when I start a new Part?

The picture above refers to Cosmetic Thread Display. Is this what you wrote about?

I assume this is the draft quality you are seeing under display style?  Normally when you check High quality, the options go away and do not return.  Is your drawing of a part or assembly?  Weldment, sheet metal?
