I believe the admins should have the ultimate right to edit or delete anybodies dashboard, take the ownership of it, pass the rights to edit to other person and share it with anybody they want.
Real world example:
We have ~200 users of the PX and approximately 98% of them aren’t that familiar with the PX interface nor are they familiar with the events that we are implementing. That’s why whenever they need a custom dashboard they are coming to the 2%-lucky-person (let’s call him Luke) and ask him to create the dashboard for them.
Since this Lucky Luke can’t transfer the ownership afterwards to the requester, Luke has to forever look at all of these dashboards as his own which disables him from looking at this own dashboards that are important for his work.
Passing the ownership to the requester would solve this issue once and for all.
However, many times other users who have their dashboards need a bit of help of tweeking some widgets so it would be extremely handy if admins could easily go into every dashboard and change/update them according to the recent rules/implementations.
