One-tap/slide delete
If I delete a text from a notification action button, it just takes one tap – GREAT! But if I delete an entire conversation from the conversation list by sliding, I still have to tap on the delete button that becomes visible after sliding. And finally, if I delete a conversation from the conversation itself (i.e. the conversation is open and visible in the app), it takes THREE taps: one to open the toolbar at the top, a second to tap the delete button, and a third to confirm the delete button.
Not sure why this is necessary when the app already provides a safety grace period by means of the 10-second undo button on the conversation list screen. It's really annoying at least to me to have to tap the delete button all the way on the left after sliding a conversation to delete it, especially if I'm using phone one-handedly with my right hand. And it's also annoying to go through three whole tabs to delete a conversation from an open conversation. since there's already the safety net undo button, maybe add an option to the app to do the delete without requiring the last confirmation tap?
