Rethink the Search options?
I do see the connexion between the two Finder options, at least as long as the user is in the "map edition" frame of mind: both options can be used to find the node you need for a move or a cross-link.
However, I'm wondering whether it wouldn't be better to separate the two Finder options, acknowledging the fact that a large majority of users will just want to navigate the map and not edit it. Such users would want to use the "Search" in order to find out what the map says about this or that particular topic, and not for map-editing purposes (i.e., for moving a node or creating a cross-link). Typically, a new Debategraph user, arriving say from the FCO website, might want to search for something like "Iran" " or "Nuclear Posture Review", or "Turkey Brazil". For such a user, the second Finder option introduces some extra complexity for no real benefit.
The second Finder option is actually very close to the Context View, and so maybe the Context View could be thought of as a specialized tool meant to help the - still relatively rare - users who are in a "map edition" frame of mind:
- "Tree up" is always visible in the Context View
- "All ideas on this map" can easily be visible in the Context View
- "My maps and bookmarks" could easily be added with an extra line at the top (at the root) of the Context tree
If the second option of the current Finder view were, in this way, merged with the Context View, then the Finder Tab could be renamed "Search" - probably a better name than "Finder". Or maybe the Finder tab could just disappear: in this case, the Search box would always be displayed (for instance just above the tabs line).
I am not sure how often it will really be useful to be able to search for "any word" from a list of words. Also, if you want to search for an exact phrase, you can just put quotes around the search expression. So maybe it would be sufficient to have a very simple search interface (a mere search box) without the 3 current search options?
