Here is my custom solution where the analyst get a modal preview window with some quick info when hovering/mouseover on a workitem title in the grid.
Included is the ability to rename a service account to something else or disable all actionlog entries from a given service account.
Settings are at the top of the custom js file:
// Needed for both name change and ability to hide those entries<br>var serviceAccountName = "domain\workflow_svc";<br>// Hide all entries made from above service account, true/false<br>var hideServiceAccountEntries = false;<br>// Name to display instead of service account<br>var newServiceAccountName = "IT Service portal";
Tested with IE11, Chrome 55, Firefox 45 & Edge with portal 7.2.2016.1
I've attached the files needed in a zip archive. To install just drop the files in CustomSpace (merge custom.js if you have other stuff there already!)
