It's a great idea, but very annyoing that many users add useless Page Notes. It would be great if we could block individual Users and if we could block public Page Notes for selected domains.
ten thousand years for Hypothesis!
First of all, let me say that this extension is very useful while I am reading papers. Here is my suggestions to improve it - 1. If I turn it on, it changes the URL of the page (I am not sure whether this happens on all the sites but I can confirm that this happens when I read papers on arxiv). So if I need to share the paper with someone, I am forced to turn off the extension to get the url, refreshing the the page/pdf twice in the process. So I am forced to scroll back to the section which I was reading. It would be better if the extension does not change the url at all.
Great way to annotate websites!
Wow, just wow! I rarely say "Everything's perfect about it" but I have to admit "Everything's perfect about it"! I just wish there were an option to highlight in green, yellow is really hard on my eye.
Incredible concept, but not usable for me. I have to re-login everyime I want to annotate a new page. Plus I just spent 15+ minutes annotating an article and it looks like 2/3 of my annotations didn't get saved.
I literally installed this just so I can turn it off on journal article pages that have it on by default. There's no way to turn it off. Reading a journal on a web page is extremely annoying when every time you click opens a bubble asking to highlight or annotate.
There is very pertinent comments: "I would pay for it, yet is free."; "Someday, it will be integrated part of the browsers."; I was looking forward for this perfect annotation tool.
Please provide the option of having the extension active by default on a webpage.
