i wanted to delete the 'all' category but what happened was all the icons that were in the all category gets spilled out into the main app menu. It's as though the icons in the 'all' category had to go somewhere so it went to the main app launcher menu... so it's like all the other categories were still there but the apps from the 'all' category are alongside it too
Good work. You could ask to be the maintainer of the packages in order to upload your new versions to Extras Devel.
any screen shot ?
