I just found a client called TWBlue. It seemed to be absolutely perfect! Then, I tried to post with it. Not only can I not hit enter to go down a line because it posts, but it literally has no function to allow me to edit my posts or comments! I can understand the first, since it was designed to work with Mastodon, but the second makes no sense to me. Still, these people are extremely serious about accessibility and actually care about user suggestions, so O I may write to them. I would love for these features to be added, since it looks like a full client.
