When using long proxy names, there is a tendency that the hostname of the host you are editing is dropped from the screen. If you are working on a tab other than the 'Host' tab, there is no way of seeing which host is being edited (without switching back and forth between the 'Host' tab). Please see the attached file for an example (actual name is redacted).
This could easily be solved by creating a hover element that shows the full field on mouse over.
I would suggest using this hover on any truncated field in the frontend (might be interesting in 'latest data' also?).
