Agreed. Also perhaps process of leaving notes and arrows might be more intuitive: - Make leaving text the default tool. "Click where you want to make a note about the page." - "Type your message now" appears there, and disappears when they start typing. (Or at least a blinking cursor.) - Hovering over the textbox reveals an fadded arrow that, that when dragged away turns into an opaque arrow that extends to wherever dragged. (Arrow and text box can be moved independently. Arrow can be deleted with delete key or dragging it to the text box. (Or have a trash icon that elements can be dragged to, or when clicked, the next item clicked is deleted.) ) Or instead of the text default perhaps have the more familiar contact us text box also next to the editor, so they can write, then place arrows to what they are writing about. Interesting project. Nice work!
