Pinboard: Collect files and links in the side panel
Forget searching for frequently needed files and links, and attach them directly to the board’s side panel with Pinboard. Besides website and online document links, you can also attach Kanban Tool tasks and links to other Kanban Tool boards.
You can enable the add-on from board Settings → Power-Ups.
To pin a file, just use the “+” icon, located in the Pinboard header.

Important: To pin a website link, first make sure that you have enabled the Web Attachments power-up.
You’re also welcome to pin files from your Google Drive, Box, Dropbox, or One Drive accounts, for as long as you have the respective power-ups switched on.
