My 64th extension has now been released. First new extension in 2 months; I hope you haven’t been worried .
Eneroth Line Up Axes is used to line up the local axes of the selected groups and components with the parent axes. One reason to do this is make the texture positioning match between groups, as faces lacking implicit material positioning have their textures drawn according to their local axes.
If you found this plugin useful, maybe Eneroth Visual Merge, for hiding the seem between adjacent groups/containers, is too.
