I would love to see longer field names possible. Currently we are limited to, I think, 20 characters.

This has been requested before, i know it is something that "would be nice" but changing this would assuredly break backwards compatibility, and field labels can be of any length, mitigating any real need to add this, at least this is the line i have heard before.

Inmagic's research asset management product, Inmagic Presto, supports field names significantly larger than 20 characters.
