I looked into the possibility of highlighting new comments when I added the indicator, but unfortunately there isn’t a support for it API-side. So we’d have to do it locally.
We are aware that swiping to collapse the top-level comment would be a useful feature and are tracking the issue here. The swipe action to collapse comments was added back in September, and isn't a new feature in this release.
To clarify - you'd have to upload the image to your instance in the browser, not within Mlem's post creator. Mlem doesn't provide a way of copying the URL of an image you attach to a post. And if you never post the image you attached, Mlem will request that your instance deletes the image.
Hey there! We’re aware of this issue. This is related to a system that we implemented hastily to get 0.19.0 support working; we’re working on a more robust solution for the next update. If you see this error, going back to the communities list and re-entering the feed should fix the issue.
Yep, this is planned!
