Highlight text or data in pdf documents opened from the web in Chrome and click the lumio icon in the top left corner. When you save a highlight from a pdf, lumio saves the whole textual content of the pdf.
Hide the save button when not needed
Want to turn off lumio? Is the save button sometimes in the way?
Right-click the toolbar icon, then select 'Hide lumio save buttons' at the top of the list.
You will still be able to save with lumio via the right-click context menu.
Find 'Show lumio save buttons' the same place later.
