The Dropbox component has 3 locations for the PersistTokens = plIniFile, plRegistry, plDatabase.
What are your thoughts on adding a fourth location where the location is specified as being embedded into the application code?
Any changes to the tokens would require an application update but that is not a disadvantage. Especially using your WebUpdate!!

This would require a self-modifying EXE. Most antivirus tools are sensitive to this. This isn't trivial and in combination with anti-virus, it is error prone.

This feature will not be implemented.
