I have used Airmail for a year or two now and I really like it. My chief reason for liking it is that so many aspects of it can be customized, particularly in terms of keyboard shorcuts. Unfortunately, some of this functionality has been diminished in the latest update. It used to be possible to archive messages in specific folders incredibly quickly, without your fingers leaving the keyboard. To move a message to the folder “work”, you would type v-w-return. Now, there is a little animation that plays after you press ‘v’, so it’s v-<wait for animation>-w-return. If you’re used to typing the keystrokes in a quick sequence and you now press v then continue typing during the animation, those keystrokes are interpreted as other commands, leading to all sort of unintentional actions. I am having to learn to insert an annoying little pause into just this one command, to accommodate this unecessary animation. It feels contrary to the spirit of the app, which is otherwise all about speed and fluency. I hope this is changed in future update. Still, overall it’s a great app.
