I would like to have a bookmark manager that can be organized with folders/tags and manually sort the items within the folder/tag. If it supports more than bookmarks (i.e. image, file), it's better. I would like to manually sort and organize the research items including bookmarks. I don't want to use to do apps cause it has checkmarks. With Airtable, Evernote, Workflowy, Pinboard, Raindrop app, some don't have browser extension, some cannot manually sort the items. Dropmark is nice and free with the browser extension but it can only show the tile layout in the free version. It's $5/month personal plan seems pricey for me.
