Bookshelf

If you are lucky you get just 20 second waiting time when you change chapter. I bought a math book so may be software make all the calculations at the same time and draws graphs from scratch. But for some reason I don't believe that it does all that. Anyway I understand that math layout might be a heavy task to some old computer but I've noticed this same issue in my laptop, desktop machine and phone. And no. They are not so old. This is very very annoying - if I didn't make myself already clear - because I have to jump between different chapters. Anyway if you don't need to jump between chapters and you are reading just pure text without pictures this might be your bookshelf. It has basic highlight, search and bookmark functions and you can select different "paper" (nice) colors and it has even flashcards - but all those great things are totally unusable because when my page is rendered I dare not to do anything else in the fear of another lost half minute.
