With this major version, we have introduced the concept of sign "types."
Currently, we have split the signs into those that are part of the official LA Historical Markers program and lumped all others together. The two different sign types are distinguished visually within the app by color. You can now specify what type of sign you are entering as part of the submission workflow, and you can even filter the main view by which sign type you would like to view.
We also squashed a handful of bugs and generally tried to improve the way the app functions.
