it did not work properly.

A simply task of editing a bookmark, I could not see how to do that. I assume you search a word say piano and you can select a bookmark with the word piano and simply modify. You can modify the title of the bookmarks this way but it does not record the changes made!!!

If I cannot figure out such a simple task, there is something wrong with this addon.

And various issues arose. I could only type pia and it would not let me type more than pia!!!
