The posting window looks ugly and does not give the cleares overview it could. It tries to show everything without vertical scrolling.
In my normal usecases it shows every line in a multiline view with up to four lines. That takes a lot of space when you have a lot of lines in one posting window and needs scrolling down. It is bad for the overview when I can not see the account number in one row because the account names are written inbetween in the same row.
My idea is to make it configurable to show all fields in one line. An maximum field width to avoid chatty descriptions taking too much space will be useful. We can also configure the order of the fields or even to omit some fields. That allows to order seldom used dimension to the far right of the table (that may be hidden) or to omit e.g. the organisation if we use only one or to omit dimensions like the campaign or project if we do not use them in normal business cases.
Other ideas to improve the situation are encouraged.
