Con Automatic bookmark organizer is unpredictable
The Auto Folders as well as the Suggested Folders features rarely seem to get it right. In one case it creates random folders that have nothing to with the bookmark in question (like creating a folder called McDonalds for a picture that has nothing to do with fast food) in the other it suggests folders that clearly have better alternatives (like suggesting the folder "Linux" instead of "Productivity" for an article titled "Productivity Tools").
Con There's no way to automatically generate thumbnails to pages that were saved without thumbnails
If a site was bookmarked before installing the extension or it was saved without selecting a thumbnail, the only way to get thumbnails to show is to go to every bookmarked item manually and editing it.
Con Poorly designed UX
The extension requires a lot of clicking to save a bookmark to the appropriate folder and navigating folders is unintuitive and confusing. For example, instead of clicking a folder to open it, an arrow next to it has to be clicked, but it can't be done from the initial view as there's no arrow next to the "suggested" folder, instead an "add to folder" button has to be clicked first to access the folder selection menu. Furthermore, a bookmark can't be saved to a folder that's open, the destination folder can only be selected from the folder that contains it.
