Doesn't highlight. So you can't see on the page what you have saved.

It works but is a bit too barebones for me to be completely content with. It doesn't sort them by time (if it does store the time at all) and it doesn't let me filter by specific webpage or a domain. I feel these features are basic & necessary for the addon to be complete.

For a big bonus (since that's not exactly what the addon does), it could let me tag the entries with custom words to search & filter with later (like "wisdom", "advice", "well written", "check later", etc.).
As a normal bonus, it could change the addon button icon if the site that has snippets saved is opened. Then clicking the button could reveal the list of them instead of going to the full addon's page & maybe even click them to go to them with highlighting (perhaps inputting them into the native word search ability of the browser would work, unless what's saved doesn't agree word for word with what's actually on the page).

It doesn't highlight anything, but allow to keep quote and extracts. It's not very handy through, because when I select something (using the context menu), I have to click on the toolbar icon to check if the "highlight" (or rather the selection) worked, and see all the extracts. When I click on a note from this page, it reopens the annotated page (but without the highlight of course, because this feature doesn't work, as said earlier).

doesn't save notes in order.... :(
