Hi there Patrice:
I am a translator from Brazil.
I've volunteered to have the Brazilian Portuguese language file for BKM updated and improved upon a bit (through a lot of proofreading in fact, although you may get further improved ones in the near future, on account of its relatively extensive size, which demands time and effort to be properly dealt with). The file follows attached. Hope you like it.
- The "Sort bookmarks", "Do not open" text strings are missing from the English source-language file, so they could not be translated (See program main window and "Export as HTML" dialog).
Also note that, although I have a posted a previous message on Sourceforge a couple of hours ago with a language file attachment, use this one that follows attached for distro.
