It would be great for Textra to be able to automatically remove its notifications when you read new messages outside of Textra. I often use AirDroid to reply to new messages, which marks messages I reply to as read. However Textra keeps its notifications in notification pane until I swipe them away manually from the phone. A workaround in my case is to allow AirDroid to forward Textra's notification to a computer and "Delete" them from there, but this causes every new message to generate two notifications on PC: one from Textra and one for a new message.
