I’ve been using #jjui for about 6 months and it’s become essential part of my daily workflow. I stopped using jj cli directly completely, jjui does everything I need perfectly, and makes dealing with #jujutsu repos a pleasure.
And it really shines when working with agents - it’s almost effortless to try different approaches with parallel jj changes, reviewing, and discarding when an agent produces crap.
I used to be a big #magit fan but since I stopped using Emacs I was on the lookout for a replacement. Nothing came close. With #jjui I feel home again. It’s jujutsu native so it works and feels slightly different than magit, but I feel like I’m flying with my VCS again :)
