Size limits on Research Notes field

I understand that the size limit on the Research Notes field is 64,000 characters, equivalent to about 16 pp. of text. Sounds like a lot, but, if a source is lengthy (e.g., book-length), I occassionally need more space. Could the size limit on this field be increased in a future enhancement? Or could an option be included to let the user increase the field size?

BTW I’ve been using EN since at least EN7 and I like EN20 much better.

Why would you paste the text in the field rather than attaching it in a document?
