Hey Kostya,
I just want to thank you for implementing message folder destination conformation/undo for "Move to folder" actions, along with deletion/undo!
This is a feature that I requested some time last year, and I'm as thrilled as a little kid at the amusement park that you've added it! As one who constantly moves messages around between more than 36 folders throughout each work day, being able to see that folder destination conformation toast helps my work-flow go so much more smoothly.
I also love that the "undo" toasts are semi-transparent...looks real sharp!
Again, I state that I'm a huge fan of your work. You continue to maintain an incredibly high standard in the cleanliness of your coding, and excellence in sensible highly functional design, customization and implementation. Your user support and engagement is still beyond exemplary.
If there were a Presidential Medal of Honor (I'm in the US) for developers, you should receive at least 5-6 of them. Oh, and you should also get a MacArthur Genius Award.
