Hello,
so things become clearer. Alexander and Steven are multi-window user and
Joost and me are single window user. Steven wants to connect the switcher to
the game list. For me as single window user it is connected anyway. But
there is a problem for multi. The switcher is also related to the main
window as the current game does switch with the actual database. And with
the changes I planning the game list is no longer dependent on the switcher.
Last point is that multi window users like Alexander don't use the game list
window in favor of the browser as stated below. Steven, you should think
twice.
Filtering on the tree data. In my private code I have a hack. If the
database is larger than 100.000 games it creates a statistic only on those
games with rating > 2300. The reason is simple. Below there is a high risk,
that the game results do not relate to the opening. So following statistics
in opening preparation have a higher risk to become misleading. This hack
triggers only for large reference databases because there looking for a
statistic over all games is in my opinion completely useless.
A good question is how a clean implementation could look like. Again the
search filter of the database should not be misused for this as it has its
own useful purpose. One possibility could be a minimum rating field in the
tree window or just a flag with a hardcoded limit or the possibility to set
a full or some attributes of the header mask... I am open to alternatives
here.

Right. The tree statistics currently refers to all games in the base
while the best games gets the filter applied. Currently if you're
searching for a player your tree does NOT reflect that players repertoir.

Well, I feel you've to resort to the way how it was done all day long:
search for the players you're interested, copy their games to (at least)
the clipbase and use that base' tree against your opponents game.
IMHO there're quite some reasons why you end up with more that just one
reference base IRL. This is just one of them.

If I got Gerd correcly once he supplied the filter patch, it would be
easily possible to have the tree doing it's bean counting only against
the filtered games. (Gerd, you might want to comment on this yourself,
you're the expert here.) The question arises indeed if this would not be
the more logical behaviour, following the filter logic. If I recall
correctly one argument against it was that you might actually not be
interested in your opponents repertoir but in the best move in your
database. And this doesn't get displayed if you filter the tree stats.
(Side note: in Scid all those things were called "searches" till now,
probably this has some meaning.)
