View / Current View / Define View / <select view> Edit

In the upcoming dialog named as the View name, click the "Fields Shown..." button.

* Note that the "Show Fields" named dialog does *not* appear nicely
  above the previos dialogs (which are almost centered),
  but gets positioned by the Window Manager (depends on other existing windows).

* Note that this dialog also is being displayed *below* the
  "Define Views for [...]" dialog.


Of course this is true for Group By and Sort buttons, too.

Also, this is true for all Evo Components. GAL.
