With today's Karbon update you can now move tasks between work items, upload profile images for your contacts, and filter Triage to only show conversations you are mentioned in.
Move tasks between work items
From the options menu of a task you can now move the task to another piece of work. This is particularly useful if you have a task that doesn't get completed in a recurring work item—just move it to the following work item to ensure it doesn't get forgotten.
Contact profile images
You can now edit the profile image for your contacts. Choose from one of the images that Karbon automatically sources for you, or upload your own.
Mentions filter in Triage
The additional filter in Triage shows you just the items you have been @mentioned in by your colleagues.
