Size of the text field for Page number Book etc

Perhaps I should be using these ‘Modifier’ fields for this? Although, its still too small.

When using the pop-up menu for inserting a new reference, I find the text field in which one enters the page number etc is way too small. Its fiddly to enter the correct page, and all the details, for some texts, etc. I would like this text field window to be extended at least twice as wide. As you can see in the screenshot, I am unable to see the long references I have to use for certain classical texts.

Thanks, we are actually thinking a lot about usability of this dialog as we are working on the Word plugin. We have not been aware of this issue.
