The way lightroom CC uses collections would work. You could even update "tags" to work like this and allow for visibility and groupings of tags in side bar to make organizing easier.
This feature is a must, that's what's keeping me from subscribing
This is something that I've run into recently. Say, for example, that I have two collections: "Inspiration" and "Music". I find a website that I think looks beautiful, and I want to save it under "Inspiration". This makes sense contextually. However, if the website that I find also has some great music that I would like to listen to, it also makes sense to include it under a "Music" collection. Keeping a bookmark in both collections makes sense, but how I access that bookmark is context-dependent.
Isn't this why we have tags?
This would make it similar to the app Keep It, where your files can be in multiple different bundles at the same time, with only one file actually existing. This takes the hierarchical tree file structure and turns it into how your brain ACTUALLY thinks. The next thing you think of will always be related to the current thought, and with multiple bundles like this, they'll all be just one click away. You don't have to have questions anymore like trying to remember a car photo but cannot recall if you saved it under "red car", "sports car", "Danny's car", "Nissan", or "Turo". Instead, any of those will find it, and it will be within easy reach, mimicking how we actually think. If you could do this suggestion of John Le Drappier, your product would become infinitely more effective.
This would be great to visually find items in multiple places
This would work great for moodboards created from images stored in raindrop already
Yes please. Currently I don’t think it’s possible to even duplicate bookmarks. Every time I try to save a bookmark again it just populated the collection it’s already saved in with the same tags. If I change the collection it removes it from the collection it was in and saves it in the new collection. I want to save most of my bookmarks in more than 1 collection. Smart collections using tags may work but then you will get all bookmarks that have the same tags vs just wanting a duplicate bookmark.
Agreed!
