Dear developers and users,
it's now possible to tweak table column visibility and position
through header context menu in WebAdmin's main & sub tabs [1,2].

This allows you to turn "unwanted" columns off and re-arrange
those which are visible to match your personal preference.

There's also RFE [3] to persist (remember) such column settings
in the browser, similar to persisting other client-side options.
