Using the tree window in SCID on a subset of games in the database With a database open in SCID, one can use the tree window to explore openings.  Among other things, it shows the frequency of each move that has been played in the current position and how well that move has scored.

Is there a way to combine this with SCID's filter functionality so that the tree window only uses the subset of games selected by the current filter?  For example, this could be used to explore openings based on 2600+ games or games where the opponents are close in rating.  

It is possible to do this by creating a copy of the database and then removing all games that are not in the filter, but this is an inconvenient workaround.  Is there a better way?
Yes. In the tree window, there is an "All Games" checkbox. Unchecking this will make the tree window use the filtered games instead of all the games.
