Provide feature to add Hours/Days as part of Task. And allow to use the information in Charts, Exporting to Excel. I am hold up with full fledged implementation due to the shortcomings of Task Duration in a Task.

There is currently NO GOOD WAY TO PRINT a LIST OF TASKS

The ability to assign a task to multiple people is a big improvement. BUT, we'd like to be able to designate a primary responsible (ie. a task lead.)

I accidentally deleted a task in Planner. The Task had screenshots and an agreement attached. Once the task has been deleted it does not go to the SharePoint recycle bin and the task, conversation, attachments are permanently deleted.

Easiest fix is to place the task into recycle bin. Work around is to place all attachments in the file repository then attach to task. You still lose the entire task list and conversations thus making this a critical flaw.

I frequently get logged out when working with Planner after some time of inactivity - this is different from the rest of the Office365 suite. While having to login again is not only annoying, I have also lost content because of this. On more than one instance I was still able to create tasks, only to find them gone after having to login again.

Please build a desktop app for Mac OS

TASK Delete - It should not be possible for anyone to delete a task. Task deletion should be restricted to the creator of the task or administrator of the plan. This has cost us a lot of time and effort and effectively renders what is an excellent system useless for managing task orientated projects with big groups of users because we have no clue who deleted a task or why or when.

It'd be awesome if you could tag another member of the planner the way you can on Facebook/Twitter/etc in comments of tasks so that they can see it.

When opening a task, please enable drag and drop files from Windows Explorer to tasks.

Now need to click "Attach"->File->browse for file.

Drag&drop for adding attachments straight from Windows Explorer works in Redmine.

It should work in Planner the more, as obviously both are MS products.

As stated before me. The labels are too small when applied. The user should be able to add or reduce the amount of labels and the user should have the ability to change the colors of the labels.

Need to be able to create a rollup summary of task and be able to print them out or be able to import/export them to excel to create a summary report.

Typing a URL in a comment does not render the URL as a hyperlink when the comment is saved. It would be much more user-friendly to render these as hyperlinks.

make someone a manager and only he can delete tasks

You enter in your outlook mail calendar and you can see all the tasks assigned to all the days according to the deadlines.

The ability to link between tasks is important.
For example, Management created a task. This will be converted to sub tasks on a sub team Plan.

Guest users should be notified by e-mail for any new assignments, due dates and late tasks. At the moment, only Members and Owners receive reminders for assigned tasks.

1. When a task is assigned to a guest, they should receive an e-mail with the information sent to their e-mail address outside of the Office 365 tenant.

2. Reminders sent to the guest's e-mail address

3. Updates to the task sent to the guest's e-mail address.

I wish to save a plan as a template with template tasks that can be individually attributed and assigned to individuals. The template tasks should contain a completed checklist.
These plans are under a main page with summaries and dashboards for all the plans below.

Would be good to have separate (optional) deadlines for each checklist item in the card.

By pasting Cnrl + V should automatically upload the screenshot as a file to a dedicated folder whithin the Office group and link it to the task within Planner
