Plugin Configuration Window

[Zelss]

A few things about these plugin configuration windows.

First the ok button is way below to the right, hardly visible. Second, it does not do anything. If i change e.g. pdf plugin settings and close the window by clicking "x". it saves changes and closes the window. the OK button loses its purpose then.

closing the plugin without clicking "ok" button should ask for "save changes?".

"Cancel" button with "OK" will be good just in case one does not want to save the changes. Ok and cancel button could be places at the bottom in the center to be clearly visible.

Title of the window could be better.e.g. Plugin Configuration
