There are four new buttons. LEFTDUMMY and RIGHTDUMMY will likely disappear soon.
And the others probably renamed to NORTHSOUTH and EASTWEST at the same time.
Putting the declarer (as 4th parameter) there at this time would likely broke some things, like LinConverter, so not done.
Suggestions and comments welcome.
SOUTHWEST=?????,????,Unknown,xx,xx,xx,xx,xx,xx,xx,xx][/SOUTHWEST]
SOUTHEAST=?????,????,Unknown,xx,xx,xx,xx,xx,xx,xx,xx][/SOUTHEAST]
NORTHEAST=?????,????,Unknown,xx,xx,xx,xx,xx,xx,xx,xx][/NORTHEAST]
NORTHWEST=?????,????,Unknown,xx,xx,xx,xx,xx,xx,xx,xx][/NORTHWEST]
All four with starting opening square bracket, of course, omitted to avoid interpretation.
