Two strings that would get used many places such as
[@app:copyright] = "(c) Copyright 2021"
[@app:companyname] = "Squaretree Software"
Can be used as [@app:copyright] [@app:company_name]
but since company name would always be used in the copyright string and the copyright string might need occasional updates such as changing the date it would be great to be able to do:
[@app:copyright]="(c) copyright 2021 @app:companyname]"
The workaround is pretty easy in this case but there may be others where this nesting would be very valuable and I would think, a pretty easy enhancement.
