Text field for whole mmb file to get owner's notes

[MlinMMEX]

Hello,
Would it be affordable to provide a text field to be able to write down notes and text (plain, at this moment) for the mmb file?

I am now missing a place to write down my log of changes to the file, as well as pending to-do list on the mmb.
How does this sound?
Thank you very much for this amazing software!
