This is just first "release" of bookmarks. Now I see that I forgot something
I can add this functionality to official iRex ipdf branch. But, I am not sure, that iRex will have it. I developed bookmarks for my self, because I suddenly realized that I spend much time just to open correct page. So, I tried. I have no experience in GTK programming, and have no time to get it. So, I created bookmarks dialog by X graphics. May be, it is not good. But I found, that dialog is showed a bit quicker than GtkAuth dialog, and I spend less time, than I would spend with GTK.
I hope, that I will find some time to complete bookmarks. Probably, at next Sunday I will add names and comments.
By the way, did somebody test it?
