You can sign and remove pages using LibreOffice Draw
you can but it has many other issues as it is not a PDF reader. It has no bookmarks, every PDF is opened editable so if there are shapes or text you can accidentally move them, there is no continuous scrolling through a document it is divided into individual pages.
PDF is simply not solved on linux at the moment.
Does your PDF Reader and PDF Editor have to be the same application?
No. I rarely edit PDFs. I sign them, bind them, reorganize pages, comment on them. I was an adobe x user then a foxit reader guy on windows, there you can do it all. There is a foxit reader for linux with fraction of the features and have crashed for me constantly (back to my original point that multi OS developments have inferior linux version)
Ideally I would prefer a single software to manage my PDFs just like for example I prefer a single software to play my different format of videos.
