This should be default in any browser. I'm not certain if the comment moderation mechanism is any good but having the ability to read users' comments on any given text on the web can be invaluable when doing serious reading. Within the first few minutes after installation, this extension already provided me insightful comments and answers.
After you annotate text, when you are writing your note, none of the text tools like "Bold", "Italics" work for me. When you hit Bold, you get * on either side of selected text. The Link function does not work. Please fix this. Also, pl add some more highlighter colors. Otherwise a good product.
It's great. Keep your good work and enhance some issues
great
Do hope you can introduce more highlight color rather than only a yellow pen.
I can't log in. I tried to make an account, I forgot I had one already. The extension told me that there's already an user with this email. I try to log in, the extension tell me that the user and password is not the right one. I reset my password by mail, I try to log with the new password, and then, it's still not ok.
A great extension, and something the web needs. This can serve as a personal note taker (although maybe other mechanisms might be better for that), or a distributed or centralized point for shared notes and discussions.
I wish I could rate this higher because, in the beginning, I really loved it. It allows you to annotate, highlight (although the highlight function acts up sometimes. You try to highlight one thing, then when you go to highlight something else, the first thing that you highlighted becomes un-highlighted). Also, it is nice that you can make page notes in general (i.e. if you want to summarize a page) or just highlight one specific word or phrase and make an annotation of that. Furthermore, it saves all annotations and highlights, even if you close the tab or turn off your computer and then later revisit the pdf. BUT, and this is a major flaw. I hope this gets fixed soon: I will be on a certain page and then all of a sudden the app suddenly takes over and moves 10-15 pages forward or backward to another page. And then I try to move back to the page I was on and the app just does it again. Pretty soon it turns into a battle of me and the app and I just want to give up on the assignment I am doing. Please fix this. I am becoming angry to the point where I am considering getting rid of this extension.
Fantastic app, i have downloaded about 10 of this extensions and tested em all for my research. Finding this one, simple, elegant and very helpful. I would love the possibility to use it with PDF files.
Great tool :-) Public read groups sounds like a good idea. Would love to see private groups too.
