I'm thinking about a special feature: links to other
games in same database. These links will be created/
deleted in game editor. One example: the game editor
has the following content:

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5
   ( 4...Bc5 [+]<Reinisch-Traxler,17,0-1> )
5.exd5 b5
   ( 5...Nd4 "The more solid Fritz variation, see
   <Lange-Humbold,34,0-1>" )
6.Bxb5 Qxd5

In this example we have two types of links:

1. The link <Lange-Humbold,34,0-1> is embedded inside
a comment, a mouse click on this link will open the
corresponding game. But this link type is possibly
superfluous, because creating this link in the comment
editor seems to be a bit complicated.

2. The link [+]<Reinisch-Traxler,17,0-1> is a solitary
link, not embedded inside a comment. A click on the link
<...> will open the corresponding game, a click on the
leading [+] will expand to the moves of the mainline in
the linked game (without comments):

1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5
   ( 4...Bc5 [-]<Reinisch-Traxler,17,0-1> 5.Nxf7 Bxf2+
   6.Ke2? Nd4+ 7.Kd3? b5! {...} 17.Kb4 c5# )
5.exd5 b5

A click on [-] will fold the link. The stored game will
only contain the link, not the moves of the corresponding
game. This means, if a game will be removed (compacting
the database), all links to this game will also be deleted.

Any further ideas or suggestions to this feature?

Cheers,
Gregor
