The clone window does not display very neatly when I open it by default.
The window should be an appropriate size to display all the text and the text should wrap if necessary (or somehow otherwise display all the text neatly).
The "Append '- Copy' to title" text is truncated at "titl", the "Replace username and password with references" text is truncated at "refere(n)" (and by the end of the window), and the "Copy history" text label seems to be chopping off the descenders of the 'p' and 'y' characters (presumably due to weird sizing).

Modify the whatever structure that UI uses to work well when resized? (Grid structure, specify a minimum width, etc?)
I'm trying to clone an entry and the box appeared but was quite ugly. :P
@Throne3d can you check if the bug is resolved for you after the last PR?
Yep, looks fixed:

Thanks @weslly and @TheZ3ro.
