Form Ribbon

I typically build a [Record ID Display].  This is a formula-text field which I use to replace the default setting of [Record ID#] as the record title in a form.  I can then customize this to include key information about the record; it's parent (if there is one) and perhaps a status (if that applies).  I always add the [Record ID#] on the end, so that as an Admin I have visibility to the record information when troubleshooting user issues.

For example, a formula-text field:

[Company Name] & " - " & [Parent Company] & " - " [Sales Status] & " -ID# " & [Record ID#]

Then go into the table-settings, click on Advanced Settings and change the Record Title to the formula field ([Record ID Display].  I always make this formula field non-reportable so that users do not use it in their reports.

I do not know of a solution to display custom-text that never moves from the Top of the Page as you scroll down.  Even if you use TABS to control how much data the user sees in each one; if you have to scroll within a TAB down below the header of the record; you will still lose whatever you put at the top of the form.  The Record Title however, is always visible.
