Hey
I'm a T-SQL programmer (MSSQL) myself, so I know that sometimes some changes require a lot of code change.
Unfortunately, I do not know the PHP language and above all I do not know the structures and processes of the given functionalities.
However, I suspect that for an experienced programmer who wrote this module and knows its process, it should not be a major problem in adding additional search functionality to the group to which a given user joined. The only question is how big are the changes to adjust the module.
I hope that this new change will be accepted and released by the team, for example: in the next edition of JomSocial or someone will only undertake a modification of JS Dating and will release a new edition regardless of the release of the next version of JomSocial.
I really care about this functionality. I suspect that many users would be happy with such additional functionality as integration with JomSocial.
greetings
