Warning About Leaving Incomplete Post

I write large announcement messages by composing them in a temp channel and making edits until they look the way I want them to. The problem comes when I swap to a DM or other channel while still editing the post. If I swap out of the current channel, all edits and alterations on the post are lost - sometimes that's a lot of stuff.

It seems like if Discord would pop up a box saying "Hey, you're about to discard your edits." would be a really great feature. Similar to the pop-up saying "Hey, you're in voice chat, are you sure you want to update?" ♥♥

Thanks for doing great work!!
