Just tried and really liked it! Thanks for sharing and welcome to SamyGO!
Some things i noticed:
1. It doesn`t support B series
2. Transparency is fun, but on my desktop controls are poor visible
3. If menu is pressed, i miss controls for navigating trough menu to be loaded automatically (smart remote).
4. Use arrows on keyboard to navigate up/down/right/left in smart remote?
5. Ch up/down by ctrl+arrows up/down?
6. Vol +/- by ctrl + arrows left/right?
7. Add INFO key to Hotel Remote (to get to factory menu on the fly: info+factory)
Othervise - great app!
