Overview
There are four ways to add data to a project:
Manual Data Entry
Import from USGS
Import from HEC-DSS
Import from CSV
Each tool opens as a component in the center panel, and each is a singleton — invoking it a second time brings the existing tab forward rather than opening a duplicate, meaning that only one instance of each utility can be open at a time.
All four are wizards operated through various numbers of steps using Back / Next / Cancel and a finish button along the bottom. The finish button is disabled until the current step validates. The finish label differs per tool and is noted in each section.
