           Summary: Usability: When selecting text with "Highlighter"
                    review tool, dragging past view area bottom should
                    scroll
           Product: okular
           Version: 0.9.2
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: okular-devel at kde.org
        ReportedBy: jrtayloriv at gmail.com


Version:           0.9.2 (using KDE 4.3.2)
OS:                Linux
Installed from:    Ubuntu Packages

Currently when selecting text with the "Yellow Highlighter" from the Reviews
toolbar, if I am selecting a large body of text and reach the bottom of the
screen, Okular does not scroll the page and allow me to continue highlighting
further down. It just stops, which means that I then have to delete the
annotation, zoom out, and redo. Sometimes, if I want to select a very large
portion of the page, I have to zoom out so much that I can't read the text
anymore. What I would like, is for Okular to scroll down the page when I drag
the highlighter tool past the bottom of the viewing area.

Second, when I reach the bottom of a page, and wish to continue highlighting on
the following page, Okular does not allow me to continue dragging the
highlighter past the end of a page and continue onto the next one -- I instead
have to do two separate annotations, one per page. 

The second issue (not allowing to continue highlighting from one page to the
next), seems like there might be a technical difficulty in implementing it, due
to the way that the docdata XML format for Okular stores annotations with a
<pageList>, where each <page> contains <annotation>'s, rather than having a
list of <annotation>'s containing <pages> elements. It seems like this would
require some modification of the way that Okular stores annotations, which
might not be worth the effort considering the benefits.

However, the first issue (scrolling when dragging past bottom of screen) seems
like it should be relatively simple to implement, and doesn't seem like it
would require any heavy overhauls of anything. Any reasons why this would not
be fixable?

Thanks,
Jesse Taylor
