TagNotate for Mac 1.3.1 介绍
TagNotate is aviewer and annotator with the unique ability to assign tags to annotations - you can create as many different tags as you want, allowing you to associate with each annotation whatever kinds of information are important for you. By selecting one or more tags, you can collect together all the annotations that share those tags (across a single document or across multiple documents), and you can even use tags to select which files are shown in the file browser, or to select the annotations that you want to export to other apps or to email.
See TagNotate in action: Search "TagNotate" on YouTube.
Other PDF viewers allow you to annotate your documents with highlights, underlines, and notes. But TagNotate allows you to tag each of these different kinds of annotation.
Need to keep track of which documents mention different kinds of things? Highlight the relevant bits in each document, tag those highlights, and see the tags listed in your tag cloud; you can then tap on an individual tag, or on more than one tag, to retrieve those highlights from each source document. By highlighting and tagging information that matters to you, you can easily go back to this information later by selecting the appropriate tags.
