Congratulations for a nice job!
I read a lot of scientific articles on real paper mostly because multi-column pdfs with tables and pictures tend to go horribly wrong with ADE. I might convert them from pdf to DjVu and read them using your DjVu viewer. My first impressions are positive, but setting the right amount of horizontal step to match the two columns (sometimes not half-half) is time-consuming. I don't understand how the "Toggle multicolumn mode", works or when it is on or off. Could you please give some hints?
Thanks in advance!!!
