A feature that I use a lot, is the keyboard shortcut V to move messages to a given folder. In Airmail 2, this used to be very fast as – I just pressed v and immediately proceeded by typing the first few letters of the folder name. Now I just upgraded to Airmail 3, and I find that I now have to wait a moment after I press v before I start writing the name of the folder, or else it misses the first letter. This is really annoying, so I hope you can make it work as well as it used to do.
