I do like them - a great idea. Thanks for the ingenuity.
Thoughts for consideration...
Ability to select/toggle on/off view for each of the various types
- they do occasionally get in the way, are unusable (dense areas) and make navigation difficult in a tablet or with mouse pointer
- maybe right click context menu|submenu with a list of the various types so each can be checked or unchecked to view (wear, search, history, favorites[the most valuable])
Key Stroke to navigate to the previous/next marks
