ECCOPro Like Easy Outlining Type for a Column

ECCOPro (See wikipedia) is an non-supported product that is still beloved by many. CODA comes close to providing the database facilities of ECCOPro. However the ease of outlining with keyboard short cuts is missing. I would love to have a column type of outline where left and right arrow keys with shift, alt, or whatever could indent, outdent, up and down could move up and down. It would also be nice to have other facilities such as collapse the way CODA collapse works, etc. This would be a real boon and could lure many ECCOPro Users, Notmap Users, Omni Pro Users, etc. to CODA. Thanks for considering this request. I apologize if this is already a consideration, but I did not see it. Thanks again. Rhb
