Already I can see that there's some form of handling for replies that are unique, and that it does show the previous post/s if you open it up, which is how it's also been the case in other microblogging apps I've used in the past.
Also interesting to see that the reply I just posted isn't crossposted to my Mastodon and BlueSky (what I currently have set up), which is neat as I expected this behavior. 😆
Another thing I'm trying here is purposely removing my self-tag to see if that will change anything? In the UI for drafting my reply, I still do see my "replying to (self)" note and it didn't remove itself when I removed my self-tag. Maybe this'll work out okay.
