Cannot use it without signing up
Conusing, not intuitive, awkward.
Cannot comment without sign up... 1 star.
If I say it's a good extension, it would not be a appropriate review. It's a legendary extension with amazing features! <3
I love it, but it's really really really annoying how every time I try to use it, I need to log in again.
Want to love it, but really need ~4 colors. Core functionality for me.
I was going to use this extension for one purpose which was to annotate PDFs, but my browser (Vivaldi) wouldn't allow it, which is a shame. It would have been perfect for me if a lot of browsers could have access to this extension.
非常伟大的理想实践者
It's a good tool, obviously, especially it's free. Thank you! But I still need two more features, please consider: 1. Support the original format, e.g. bold, newline, list, etc. 2. Automatically highlight the lines after openning a page, and without showing the drawer.
Might be best there is for collaboration. Wish it had more colors and more visible annotations (text on hover? anything, really). It would be nice if it had some sort of local storage cache, so it doesn't take 5 seconds to load what I just annotated.
