Hey congratulations, I love the ease of use and the aesthetic of this app! A few suggestions to improve quality of life:

1. Add hotkeys for each tool

2. Make delete actually delete things rather than going "back" in the browser

3. Make escape return the user to the "move" tool

4. When you use the "add" tool and add something, the menu closes but the tool stays selected at which point clicking it again deselects it rather than reopening the menu

5. Don't export the "cursor" square when you export the diagram. Perhaps also an export to image rather than svg would be valuable for the kinds of purposes people would use this tool for

At the moment the tool looks great and gets the job done, but I find myself hitting a wall in terms of what I can do with it (mainly around those points I've mentioned).
