With the flag ENTRY: Text Book == Pretty Print == 2D printing template, The expressions of extraction of elements or rows of a vector, matrix are displays in history without pretty print

[[a,b],[c,d]] [2,2] => at( [[a,b],[c,d]] [1,1] ) => a

the show linear (algebraic == 1D template), also is changing the values of the indices, this creates confusion:

index [2,2] => (a)

Index [1,1] => (d)

Also to copy to input line, the subindex is in the center of the array must be at least at the bottom

at([[a,b],[c,d]][1,1]) [enter] returns at(a) ??

at([[a,b],[c,d]][0,0]) [enter] returns undef ??

Please complete the pretty print of extraction of elements in 2D format

Annex images of the hp-prime and tivoyage200, this last is 20 years old, with full pretty print

Survey: is important to you, have all history in pretty print?
