This used to be possible by right-clicking column headings in the attribute table, then using the menu that appeared to produce a checklist of fields that could be unticked & re-arranged.
I've updated to 2.14.22 and the right-click functionality has vanished! Searched everywhere I can think of, can't find these settings or any clues in changelogs.
I'm sure I'm missing something here, can someone help me out?
