description@jjba23 You beat me to it :)
I have an unpublished project that is also supposed to be a set of SXML-based user interface components...
One thing I see, Josep, wouldn't it be better to omit the hyg- prefix from the names and leave users indicate a prefix of their choice when importing the module? Like
(use-modules
((hygguile components) #:prefix gui:)
(gui:icon-button ...)
Good luck with your project :)human idhygguile-203
