Sub tag / tags in tree structure




I have been used PP for 40 days and finally made up my mind to give up using Papers and join PP’s family :smile:

There are too many tags (>100) in my PP and they are used for quite different purposes.

For example, I set best paper, dataset, demo, impressive, or other words as a group of “feature” tags; approach 1, approach 2, approach 3 to mark papers that using different approaches/methods; and project 1, project 2 to mark papers that are related to some on-going projects …

It will be much more tidy in the sidebar if tags could be presented in a tree-structure layout.

Thanks for your hard work! :smiley:


Great to have you on board. “Folders” are basically hierarchical tags (or labels as they are called in Paperpile). We have added them exactly for the reasons you describe. Many users use folders in combination with labels. You could have a “Project 1” folder that contains papers labelled “Impressive” using your examples.

You can put a paper in many folders so they really behave like labels.


But, labels are much more BEAUTIFUL than folders :joy: :joy: :joy: :joy: :joy:


Hello Stefan!
Tag groups are still a great idea. Folders are natural to use for project management, I understand that paper can be put in many folders.
Tags are great for searching your library by tag combinations. Tag groups may just make tag organisation way more clean as it was said above you may have “method” tags “subjective opinion” tags, “object” tags and so on. Currently, I have to regularly delete lots of tags just because the tag panel is getting too large to navigate. I either need different tags for different projects or tree of tags to suit all projects.
Why can’t it be done?
Edit: Maybe just add the ability to change color of folders as they are essentially labels with subcategories. Color coding helps a lot
