If you're looking for a smart and visually appealing way to organize links, files, and notes, check out
Dropmark.com. Not only that, but if you integrate with Slack, you can keep track of your team's Dropmark activity. By connecting your Dropmark collection with a Slack channel, you'll receive notifications when new items or comments are added to the collection. To set this up, open the collection you want notifications for and click the gear icon in the header to access settings. From there, go to the "Integrations" tab and click "Add to Slack." It's important to note that this feature is only available for collections owned by a team; Free and Personal Pro plans don't have access.
