Etymology is how words relate to one another, right? But when you search a word in the main search bar, this is the only thing saved in your search history. Once inside the matrix, if you click a words link, there is no way to go back later and see the trail you followed. Maybe I just haven’t found it, but could you add either a history button or perhaps (in the drop down under the main search function), include the words link-searched in a different color under initial word searched?
I think this would help the user to see how branching works both linguistically and metaphorically, but it would also help you pick up where you left off better.
Cheers! I love and recommend etymology to everyone I know!
