i don't really care lol.
if i were to write in a journal though i would like to be able to use my mouse to LITERALLY write stuff on the pages in the journal!!! (pc user here)
i mean, if we're able to write in the journal let us WRITE not just type.
ALSO if writing in the journal is in i could see it being very time consuming for console users (especially if you go the route i suggested an literally write in it).

I doubt it. It's not a viable option for consoles & everything has to be "fair" or Bethesda will have to deal with a lot of whining.
