I think that no need to resolve this task

We do not use columnname_UU fields to search and identify records.

When a table has a lot of records, these indexes greatly increase the size of the database. We partially remove indexes from columnname_UU

I think that no need to resolve this task!

It works also when I create table from iDempiere using button 'Synchronize column'

I think should add a gear button to call "Create Table Index" in window "Table and Column"
at the moment, when i create a table, run "create column from db", non index is create. i must go to menu to call "Create Table Index" process.

Really. Create table must autofill uuidx definition in iDempiere interface. Not only in database.
