Do not deprecate viewing work items in VisualStudio
The web view of work items is woefully inadequate. Space is given to areas that have little significance while key areas are squished into a corner to the right. Cannot customize the view and performance is dismal.
In VS 2017 the work item content can be displayed in VS, which has a far superior view. I strongly recommend keeping the VS view. Or at least replicate it 1:1 on the web portal.
