Feature request

Warn users when adding a duplicate bookmark. This would show them where that link already exists, saving time from duplicate cleanup later on.

In this time, I am on the horns of a dilemma cause I want to add my bookmarks into multiple collections without duplicate them. I'd like that feature as soon as possible =)

parent & children tags to form a more useful taxonomy

Use machine learning and neural nets to use tag generative tag clouds based quick scrape of the headers, title, content of the website and use user feedback to classify the data and train the AI. You can then use this same neural to be trained for collections and nested collections, etc. I think this feature is very useful because bookmarking is easy but organizing bookmarks is like looking for needles in haystacks. So much tedious tagging and collecting can be automated with user feedback to classify AI predictions with confidence.

Like "Smart playlists" in iTunes. You create conditions (topic, title/description/text contains string, multiple tags, type, date..etc...) and all bookmarks automatically puts to specified collection. Think of it as "saved search"

Being able to choose a different color for each tag would make it much easier & more efficient to (1) find the tag you're looking for from the list on the sidebar & (2) find any bookmarks with a certain tag from a collection. I know you can just use the tag in the search bar to filter the collection, but sometimes I want to still be able to view the whole collection simultaneously. Plus it's just slower to have to type in the search and wait for it to load, and then maybe go back to the whole collection if I didn't find what I was looking for.

I need a way to generate on request a summary of an article. Something like https://www.scholarcy.com/ integrated into Raindrop would be amazing. In terms of going beyond bookmark management and moving more towards knowledge management and knowledge generation, such a feature would be extremely valuable. Obviously it would imply an advanced subscription price.

I first encountered deeplinks in craft, and I think its a great idea, it allows sharing between apps, so you can easily get to where you were if it’s important. Like maybe you want to make a to-do to look through a certain collection, and you can make a deeplink of said collection and then open it from the to-do.

The ability to make a note from text only, no URL or file. This could make it a serious evernote/google keep replacement.

It would be nice to archive read bookmarks, so we can track what was read and what's on the reading list.
