Works exactly as I expect it to, and so does every one of its features.
I especially like the Quick Reblogs feature, and I don't think I can use Tumblr at all without it. It's a complete gamechanger. Same with Access Kit; I like having the alt text in an easy to see spot.
It's all very useful, and I haven't even touched the tip of the iceberg with the features I use.
I will definitely continue to use this add-on.
