The base app.

When edit table definitions, as you change col's field type, under Fields
Properties (bottom of the screen) different property GUI components are show up
in the bottom of the form depending on the field type.  This is really funky to
the eyes.  I think a better design is to have them all shown up and keep them in
a same position/order.  However, enable and disable them depending on the type.
 You can also have only a few different list (such as numeric list, character
base list, binary (object, stream etc) list and datetime list.  If there's more
fields than space allow, use scroll bar (like in a table view).  I don't think
space is a constraint here. Doing this reduce the stress of the eyes and making
working with the Base a pleasant experience.

(You could say this is an RFE, but it could also be a design bug).
