    Trying to use the pi product from the right-hand side palette gives me "product(" and not the pi product notation. Is this a bug?
    Also the sigma sum in the same palette gives me a sum(1), and not the sum(4) with the sigma notation.
    I´ve already read that:
    >Function sum(1) now built-in to the program;
    I think that sum(4) is more important than sum(1), in the right-hand side palette.

    It seems that it is a bug, unfortunately.

    I suggested to Andrey the introducing of sum(1) operator for its frequent use. I agree that now might be a bit confusing to choose the sum(4) from the function list, or to type sum( or choose summation from the palette and then to type four arguments. On the other hand there might be another confusing side effect when making sum(4) from sum(1). The summation could be made without brackets. Look at this simple example:

    x:mat(1,2,3,3,1)

    sum((el(x,i)+7),i,1,3)=27

    Contrary to the:

    sum(el(x,i)+7,i,1,3)=27

    This was made from sum( and putting four arguments:

    sum(el(x,i),i,1,3)+7=13

    This is made by choosing sum(4) and then adding 7

    The sum(1) operator is useful and I am grateful to Andrey for introducing it, but unfortunately it seems some new side effects appeared with it.

    Yes, will be fixed soon.

    Agree with you. Will correct this as well.

    Thanks for the explanation; about brackets, maybe they use some graphic space in the formulas, but they help us to avoid confusions when doing math operations with different expressions.
    Brackets are for math what units are for science and engineering.
