My 2c is that the Pocket interface shown above would be a better way of adding Labels within the Paperpile app too. It looks similar to the way bookmark tags are added in Firefox i.e. a comma-separated list with autocompletion. In contrast to a single keyboard shortcut or click and then immediately typing to add a set of labels, at the moment in Paperpile for each one in turn I have to:
- click Label search
- type label to discover I don't have it yet (I have many), select and copy label
- click add label
- paste label (or type again)
- confirm creation
- drag paper to label
I find that labels are incredibly useful as a way of tagging papers with what I find important about them and it would be great if it were easier!
