Hi Bulia, sometime ago we discussed the idea of making a default document open when inkscape is first installed, perhaps only opening on the first time use of inkscape, perhaps until the user changes their default document settings.
The idea was to have inkscape check for ~/.inkscape/default.svg and open that for "run without any parameters", and if ~/.inkscape/default.svg were missing, to use the system wide default.svg given in doc/default.svg. This gives us the ability for users to start with their prefered document options (such as page size, colour, etc). The tutorial should explain how this works so that the user can change the default easily (checkbox in save?).
I'm suggesting we try and get this in for this release, particularly if someone can work on the tutorial to explain some of the features that people tend to miss when they first try out inkscape(knots, offsets, printing to .ps). I'm writing to you because you would be the best person to implement the logic for this (I think?).
