Why does it happen that whenever a doc file starts getting longer, the editing to it keeps getting slower and slower and if it gets the size of more than 600-700 kb, it gets even extremely painful and annoying to edit it? Moreover, if I use Hindi fonts, the process of editing gets too painful very early. Will only recommend this app if your docs size are usually very small less than 200-300 KB or you should break your long doc file into several small ones if you want and love rapid editing.
