You are correct, but the .tsv file is very easily imported into Excel, where you can manipulate it however you desire, including creating charts, performing statistical analyses, etc. Manager is an accounting program, not a presentation program.
Separate listing of individual bank accounts on a balance sheet is not normal accounting practice. Look, for example, at balance sheets presented in annual corporate reports. You never see individual accounts listed. If you want this type of specialized information, you will need to create it yourself. You can do that by exporting necessary information and creating reports outside Manager.
It would be impossible for Manager’s development team to envision every report every company might want to use. So they stuck to the standard ones every company needs and provided the export feature. This is meant to be a simple program. Many users chose it for that reason. There has actually been backlash on this forum when people have suggested making it substantially more elaborate. Nevertheless, features keep seeing added and capabilities are constantly being enhanced. If it meets your needs, welcome to the forum. If it doesn’t, perhaps another product would be better for you. I think, however, you will find it quite useful. There are several frequent users of the forum who use the program for club accounting.
