It would be really handy to be able to drag files from the desktop, Windows explorer, etc. and drop them into the Prince interface (i.e. the Documents and Stylesheets panes). This would be especially useful because it seems that the 'Select Input File(s)' dialogues default to displaying the 'C:\Program Files\Prince\Examples' directory every time the program is started, and there doesn't seem to be any way to chance this: this directory is not where I would naturally expect to store either my content or my stylesheets and at the moment I have to leave shortcut links there to get me to the right places to find my files!
Drag and drop support
Sorry for the inconvenience, we'll take a look at this issue.
We have now released Prince 9, which has an entirely new Windows GUI that supports drag and drop for files.
