Can't do multiple annotations???
Amazing, but please add an option for BRIGHTER, CONTRASTING highlighting! I have a fairly high brightness monitor, and I can barely see the yellow highlighting.I literally highlight the same spot multiple times to see it better!
Exactly what I looked for and even better. It is interesting to see that someone already read the article and had some thoughts
Promising but with some major holes. Once you've annotated a file, there is no where to save it (no dashboard or list of files you've worked on). The help doc on printing didn't work. The overlay doesn't show up when you go to print. So take all the notes and they are stuck on your screen. Also, there is so little for help documentation. Not helpful as a research tool yet. Could be really cool. Just missing some key pieces.
Exactly what i was looking for. Pat on the back!
Warning. You need to create an account before you can do anything. That is just crazy, why do i need to signup when I just want to create labels to my pdf files??
Very promising. Waiting on functionality like local storage of posts, group post management, bar location options, and more.
Very handy app. Request: a dashboard overview of all notes made.
Love this site/plugin - collaborative commenting without limiting fee structures. If I had one request though, it would be an option to have the plugin automatically activate for pdfs.
I will rereview at another time but it looks really promising!
