The newly introduced dialog shows the extension name per URL with access to the website. This URL can be long and resize the dialog while loading. For example "OpenOffice.org2GoogleDocs - export & import to Google Docs, Zoho, WebDAV". So we should either
a) abbreviate the text with ellipsis or
b) wrap it, if possible for URLs, or
c) use an ordinary label and add the link somewhere else (behind the name as [Link] or in the list of properties.
I tend to c).
Has been implemented with another patch.
