Expand/Shrink selection dialog may be improved

[Octagon]

Expand/Shrink Selection dialogs provide the Define button that opens the same form that Search (Alt-F7) does.

With Alt-F7, the form has the "Start Search" button in the General tab and allows to do a one time search easily. With Expand/Shrink, the form has the "Save" button in both General and Load/Save tabs, making a one-time expansion or shrink hard.

So, why not make the form behave like in Search and have "Expand" instead of "Save" in the general tab?

Why not add a "RegEx" check box to the Expand Selection dialog?

You already can use regex by prepending it with the '<' character; it's described in the help.
