Many new features for v1.1 version. 1、Impored stability. 2、Simplified GUI,no image shown,status light(red:busy, green:finished) instead 3、Recognition timeout(8s) to prevent long period of invalid calculations 4、 Window always on top unless you minimize it. 5、Just release the left-button to finish snipping, no need to confirm. 6、Shortcut F2 for snipping. 7、Double-click the 'copy latex/mathml' to enable or disable autocopy. 8、History button to copy all the history fomual;Double click to clear history.

Issues: 1、No idea about how to prevent renaming operation from shortcut F2.But luckily renaming is not used very often(hope not just for me!).
