The design looks great now. Thanks for fixing this quickly.

I noticed some inconsistencies with user editing.

1. In Admin/Users, user editing still has Location: X instead of under: X.

2. In UDW, user editing has visible tags.

QA Approved, second issue will report separately - this information was visible there even before the design change

@NataliaBecla @dew326, could you discuss two issues reported by @katarzynazawada? We should address these inconsistencies now.

[IdaDraM]

We should update all screens with "under" without ":" instead of "Location:".
Also, all the time we should use one template, no matter in which flow user is (on the fly, UDW, regular content creation)

[lserwatka]

Question also about the buttons, why do we see different labels on the buttons "Update | Cancel" vs "Save and close | Discard"? @NataliaBecla @dew326

[IdaDraM]

This is also a left over from simplified actions feature, need to be reported to fix. @katarzynazawada do we have it already reported?
