Description - While "last updated by" field is available on a task level it doesn't always render correct information (as confirmed by WF support)
Why is this feature important to you - We would like to quickly check who was the last user posting update on a task, updating timeline or updating any of the custom fields. This is critical for easy handover of tasks between users
How would you like the feature to work - I would like to have a field that would contain meaningful information regarding the task I'm looking at. Last updated by means last user who done anything relevant for this specific task I'm looking at (only!), e.g. posted an update, updated any field (including custom ones), modified the task timeline.
Current Behaviour - Currently this field will also capture changes that happened elsewhere, e.g. if someone updates another task's timeline that will result in project timeline update (in which both tasks sit) than Last Updated By will display name of a user who updated another task, which can be really confusing. In other words, in worst case scenario Last Updated By essentially is a field Someone updated Something Somewhere. it's for user to guess what happened and having this field is pointless.
