The new version is pretty fast.
I would like to suggest a feature as well and I guess some of them have already been mentioned earlier in different ways
1. Since we are using the keyboard either ways, it will be better if we can select the filtered application using arrow keys (Up or Down) and selecting enter key.
2. A possibility to add speed App selection option example assign 1 for calculator, 2 for web browser, 3 for Alarm/Clock, etc

Thanks.
