A extensão é muito boa, especialmente para anotações em leis e pdfs na web. Contudo só não dou 5 estrelas pois gostaria que fossem incluídas novas features na ferramenta: - A inserção de cores nos highlights ajudaria muito, para identificar das demais marcações; - Nos comentários, poderia, também, ter cores diferentes e highlights neles, já que, acredito eu, é possível adicionar essas funcionalidades no Latex ou Markdown.

I really enjoy the this extension, it's very useful and easy to use. My only issue is it's a little buggy. Whenever I click into a different tab and return to the pdf, the pdf doesn't load but only on pages I've highlighted. Occasionally, the highlight/annotate buttons will stop appearing when I select a sentence. The only way to fix this, that I've found, is to fully close the pdf tab, and return to the original website that I accessed the pdf on, and load it up again. Ultimately, I really like the extension but it needs to some kinks worked out!

Hypothesis is a very useful system/service for highlighting and annotating webpages and PDFs. The extension itself could do with some refinements. It would be great to have a way to activate it for all webpages (a mode in which it's just ON during entire browsing session, or until manually turned OFF again). Currently I have to turn it on for every page, which is a bit tedious when doing a lot of research with potentially tens or hundreds of tabs.

Fantastic but wished it stayed active or automatically activated on every page. Rather inconvenient to activate on every single instance desired.
