Hello,
Thank you for providing this extension for Inkscape users!

This is just to let you know that most 3rd party Inkscape extensions, like this one, probably will not work with the upcoming new Inkscape version, the long-awaited version 1.0.

Here is the info you need to update this extension, so that it will work with 1.0 and future versions.
https://wiki.inkscape.org/wiki/index.php?title=Updating_your_Extension_for_1.0

If you have further questions, you can contact Inkscape developers via mailing lists (https://lists.inkscape.org/postorius/lists/?all-lists), forum (https://inkscape.org/forums/extensions/), or the chatroom (https://chat.inkscape.org/channel/team_devel)

If you have already updated it, please disregard this message.

All best,
brynn

Little adjustments for InkScape 1.0 (by the way i am still not 100% sure for what to use :-D)
