Ability to edit all Timeline entries

I could see a variation of this request being a surrogate (like someone's EA) to edit on your behalf. Perhaps the permission is universal for an Admin role but also each user could enable or disable having someone act or edit on their behalf. 

+ 1 As an ADMIN, I would love this!  There are times that Managers are giving Demos and create 'test' entries - and later ask me to delete them.  In order for me to do so, I have to log in as them - it would be awesome if I could just stay under my profile instead.

This would be fantastic! We are trying to use Timeline for a specific type of request for help internally, where the CSM documents the details and reviews with their manager. Once the manager approves it, the manager will create a task out of that Timeline activity for another group to review and assign out, documenting the timeline activity accordingly (e.g who it is assigned, when it was assigned, etc.).

this would really help us! if you can speed this up or share a status would be great

+1, if we could add this functionality, albeit with role-based access (RBAC) so that I as admin can grant access to A to edit timeline entries by B and C, but B only has permissions to edit for C.

+1, this would be a great feature, especially with the new tagging functionality!

Not saying that this is necessarily the approach we should take on this, but here is an example of how SFDC handles this with Chatter posts: https://releasenotes.docs.salesforce.com/en-us/summer15/release-notes/rn_chatter_feeds_edit_posts.htm

Interesting thread - Is it possible to have multiple gainsight users (eg dual CRMs) edit timeline entries for the same account - Not sure if there was a soluton provided - thanks in advance

This came up today in support. Would be nice to let admins do this!

This came up for me today too. My use case is that the user is no longer with the company, and we need to go in and mark a flag on several activities to adjust reporting. I also had a request from a manager to be able to adjust for their employees as needed as well. For example, we have a Risk activity that the manager might need to add additional details to the dropdown fields available. The manager also requested the ability to move a Timeline activity to another CSM. Happy to provide additional details around the process to explain the use case better.
