Making the most recent selected tool last until explicitly cancelled (by right click, for example) may help, but back to learnability, the knowledge of 'right click to cancel current active tool' needs to be learned somehow.
- In the collaborative or publish mode editing page (screen 4), the interface does not provide a summary of all edits and the user they belong to, the user has to select an edit to see its user. Which might be inefficient when the user wants to view just a single person's edits, or the differences between her edits and others'.
