Field notes
The homepage organizes the collection by task area and also offers scenario guides that bundle related estimates. One guide covers measuring a room and working out wallpaper, backing board, and paint quantities; another brings together soil removal, gravel, concrete, and slope calculations for garden work. A personal section says starred and frequently used items appear together, and the site links to updates and tool requests.
