In most of these s/w, PDF needs to be converted as PS/ background
images and then edited. E.g GIMP brings them in as images. This is a
big issue when we have multi-page documents. If these were annotation
elements, then we can turn their visibility on and off, skip from one
to another while reviewing feedback given as annotations etc. Filling
up forms can be met by ftpsed or pdftk etc. as we do not need
extensive annotation capability. Comments and notes are the one used
most in reviewing. Arrows, box markers, highlights and link embedding
are use less but are important nevertheless.

As far as I've read, Okular does not have these features. It, however,
has the capability to read/render different formats. This makes it an
interesting platform for review/ annotation across multiple formats.

I did not know of Xournal and it does seem to explicitly support PDF
annotations. Need to check that out.

I had not dwelled much on PDFEdit earlier as it was described as a
library. Seeing it now, I see a GUI thingy. Need to explore this too.

Given all this, I still think it is a worthwhile project for some one
to take up on Okular.
