FontForge: How to add a hidden personal info text

Is there a way to add a hidden info-text in FontForge? I think, I could need that sometimes.
I mean something like that:

Hint 1: I generate that text with a external graphic programm, not with FontForge itself; because that's my question how to do that.

Hint 2: The info text should be for own work, not for read out etc.

Hint 3: I mean info-text in the displayed area, not the comment function under 'glyph info'.

As a FontForge developer, I guess the best way is to make a point with a really long name. A single floating point shouldn't mess anything up, especially if it's inside the bounds of the left and right bearings of the glyph.

So, go to «Point→Name Point». If you want multiline input, copy and paste from e.g. Notepad++.

I noticed that it seems to render multiple lines in the wrong place, which seems to be a minor bug (I'll open a bug for it done: №4420), but you can just move the point up, or use multiple points floating at the right side for multiple lines.
