...  which  you  can  already  do.  The  unit order in the uses clause
already  determines  which  identifier  is  chosen  when  you do *not*
specify  a  unit  explicitly.  So just make sure that LCL's TButton is
always  the  default  one  and  you  can still use your own TButton by
prefixing it with your own unitname. All you want is already there and
seems to cover 99% of the usecases.
