Yes, you can see the total upvotes (minus downvotes, if applicable) on Jerboa. I'm using it rn. It's on the right side opposite the commenter's username.
There's def a bug in current jerboa. For op I see totals without voting. For your comment I don't see them if I don't vote. If I upvote I still don't see them but if I downvote I do
Seems like it will show the up and downvotes next to the arrows if there is at least one up and one downvote. If there are only upvotes it will show the total upvotes on the top right corner of a comment.
