I have an observation regarding the UI, for example, in the form view I think that it is not necessary to limit the numerical fields to be smaller. There are monetary amounts that exceed millions and you cannot see all the numbers (even worse the decimals). The default size may be current, but it would be great if we could use some attribute in the form view definition that allows us to make the fields longer (for example, until we reach the length of the Many2One fields). The same for selection fields, date fields, etc.
