Checklist of changes to be made:

Other new methods

Overall things:

figure out which units everything should be in
create methods for conversion

Create PDF view/creation for:

DSOs
ObservingLocation
Observation?
- This would just be a printable form.
- Fill in things like ObservingLocation metadata, date, etc.
- At some point add in metadata for photography...
Planets
Overview
- Somehow figure out a subset of DSOs
  - maybe have PlotView create a second form to select DSOs to add to the Overview?
  - short-hand observing form? (which things in the list did get observed?)

Environment

Create ability to set "dark mode" on server startup.
- Change global style/CSS to support this.
