The configuration panel of express VIs has the [X] disabled in the upper right, but contains standard [OK], [Cancel] and [help] buttons.
Every computer users is familiar with the function of the window close button [X], and for convenience it should be enabled unless there is a very good reason to disable it. Such a reason does not exist for express VI panels. Pressing the [X] should act indentically to pressing the [Cancel] button. Note that even the <esc> key is already bound to the cancel button as it should!
So why is [X] disabled? This is unecessary micromanagement of the user! Do it like this, not like that!!! (slap on the hand!)
Users should have all intuitive and typical methods available to cancel out of an express dialog:
Idea summary:
The configuration panel of express VIs should have the windows "close" button ([X] in the upper right) enabled and when pressed, it should act identically to the [Cancel] button on the panel.
