Moving messages is an important part of managing your email. Within Mailspring, you can move messages in a number of ways:
1. Click and drag an individual thread from thread list into the left sidebar to place it in that folder / label.
2. Click an individual thread from the thread list and use a button from the action bar at the top of the screen to archive it, move it to the trash, or choose a destination label/folder. (Pro tip: you can use the "Change Labels / Folders" shortcut to open the "Move to..." picker with threads selected!)
3. When viewing a message, use the action bar at the top of the screen to move the selected thread.
4. Swipe left across a thread in the thread list to snooze it, swipe right to archive or move to trash (depending on the Preferences > General > "Swipe gesture and backspace / delete move to trash" option)
Pro Tip: When viewing the thread list, shift-click or command-click a set of threads so you can move them all quickly.
