Before submitting a new feature request, please make sure that there is no such request already present. You can check that on the list of not implemented feature requests at https://dev.copyhandler.com/issues/?filter=10400.
Submitting a feature request does not mean it will become part of the program - it may or may not be implemented in the future. It would certainly depend on the time it would take a feature to be implemented, free time of the developer, etc...
Otherwise you are free to submit your request.
Copy Handler uses an issue management system located at https://dev.copyhandler.com (powered by Jira from Atlassian). To create a new feature request, you need to have an account there. Please create it if you don't have it already.
After filling in the required information (please try to describe what you mean so that any uninvolved person would understand) press "Create" to open the feature request.
