@Wikiwide: I'm glad to hear that my post helped you

I've just tested installation of mbarcode now and it seems like the Recommends field in the deb package does nothing. In other words, all plugins, including the standard ones, have to be installed manually by the user - which is not very user friendly.

So the best solution is probably to bundle all the standard plugins into the main mbarcode package, like joshn53 suggested. I have done this now and just pushed an update version. Let's see if it works as expected

I've also set it to conflict with the old plugin packages, so that the user does not install them side-by-side with the bundled plugins.
