Popup message enhancement - show message "This tag NN is not used in Message M in FIX Version X.Y"

Imported from previous forum

I would like an enhancement to be made to FIXimate - show message “This tag NN is not used in Message M in FIX Version X.Y” when user has entered both - a “Message by Type” (35) value and “Field by Tag” value then pressed Enter on the search fields given in the left pane of FIXimate.

A sample painted bitmap of an imagined FIXimate message using the above feature is shown at

and I have used the Message and Tag example from my previous discussion at
