The budget planning interface allows you to hide table columns and show them again using a pop-up menu. Currently the menu lists all columns whether or not they have been hidden. It would be better if the menu were populated dynamically as individual columns are hidden.
Still valid.
The interface here changed. There is no "show column" anymore. The columns are simply listed with checkboxes. Checking/unchecking the boxes will show/hide the column. I don't think this is still valid, but feel free to reopen if I misunderstood.
