These extensions are not well maintained and a bunch of cruft has piled up by the multiple switches of technology over the years. This is a list of some things we should probably clean up a bit ?
[ ] Make ElectronPdfService not rely on Collection to add the Print/Export menu T256071
[ ] Should add it's own download as pdf item
[ ] Should remove the download as pdf items from Collection when present
[ ] Both sections should use the same id
[ ] review if the correct hooks are still used to modify the sidebar
[ ] Set wgCollectionFormats to empty array for WMF. This disables the download as pdf link from being added. T370740
[ ] Remove electron service stuff for what is now handled by Proton
[ ] Rework electron extension into a print/export sidebar extension ?
[ ] Remove all Pediapress print logic from Collection
