load bigger (128x128) icons on BlackBerry? 10;
removed printing related items from menu as there's no printer;
made dialogs to be shown maximized;
made solution graph smaller;
made font smaller;
made output text color black;
start editing table cells on single tap;
don't show keyboard in about dialog.
