jump to page # or percentage of text
I'm reading a long novel in ReadLang. I lost my place (50% in) by accidentally jumping ahead to 84%. It seems there is no way to go back or forwards other than one page at a time. The app needs a "jump to..." feature or slider like other eBook readers.
Also, ReadLang now thinks I have read 84% of this book which I can't change.
Next time you (or someone else) get in this trouble, I think editing the number in the address (after "/from/") will be quicker than going one page at a time. You have to guess the number as if you were guessing the right page in the dictionary.
I don't know how it is with the progress percent.
