[Sugar-devel] [DESIGN] Browse PDF handling

[Anish Mangal]

Hi Manuel,

I think (as I pointed out in todays development meetings[1]), that
this proposed behavior is somewhat of a regression (over browse 129
atleast)

In v129 to view a pdf, I first have to save it to the journal, which
it might be seen an impediment to have to save content before viewing
it, its useful in places with intermittent network connectivity. Sugar
in general follows the principle of saving everything being worked
upon to the journal as well (automatically in the background).

With this proposed change, we will be opening pdfs in new tabs, but
they will not be saved anywhere by default: not in the browse activity
instance and not as a journal entry. The kid will explicitly have to
save the journal entry by clicking on the button.

The counter argument to this is that browse does the same with
webpages (i.e., their content is not saved). If you dont have internet
connectivity and try to open the browse activity, those pages wont
load. While I consider this to be a usability issue as well (though
not pertinent to the current proposal), I think of pdf's to be
inherently different from webpages, especially considering that kids
would be reading educational content in those pdf's.
