Its very smooth running but I am not able to add multiple files(Wikipedia and Wiktionary) simultaneously. At one time only one opens and not able to add other in other tab so as to switch easily between tabs. To use either I have to first select that file and load. Please make possible to add and and load multiple files hence providing option to switch between tabs. Edit: It still cannot handle more than one file at a time. You replied you will fix it by end of 2016. Please fix it.
