I really like how smooth this is on ao3. You press the checkmark or x button and it quickly marks the fic with whatever status you've changed it to and I like how unobtrusive the star rating is when you're scrolling through a list of works and the highlighting of works is cool.

When opening a fic there are buttons at the top where you can mark the status of the fic (mark as read, chapter read, do not read, re-read) and they fit really well, but maybe a little too well. I get the 'mark as read' button confused with ao3's 'mark as read' button all the time. I wish there was more visual distinction between the two before you press on them, not just after.

I like how everything is stored locally and that it offers a google doc sync option (I haven't tested that yet but I'll edit this when I do), however, I find it kind of underwhelming, especially in comparison to other fic trackers. I wish it collected more metadata and 'my notebook' had filters or tags you could apply or sort through, for example.

I haven't tried any of the premium features (i'm not really interested in highlighting fics or whatnot, but I appreciate how it's just one purchase), so I can't rate how well they work, but this does what it does well, even though I wish it did more.
