Hookmark Version 7.2.2 (6644; Integration v. 423) is now available as a download and in-app update. We fixed these issues:
• Hookmark does not work with the latest MindNode Next
• Hookmark does not work with latest Soulver
• Hookmark does work with latest Merlin Project
• Dropping 3 files onto menu bar icon does not hook them together anymore
We have submitted Hookmark 7.2.2 to Setapp for review.
Meanwhile we’ve been busy working on 7.3
