Please, tell how to merge 2 projects. For example I have one major project with 4 forms (Form1, Form2 etc.). I also have made another project (in different folder) for testing purposes which contain one Form1. I want to add this Form1 to my major project . How to do this job?
I can add a form (it will Form5) in major project, close Lazarus, then replase unit5.pas and unit5.lfm from another project. But how to replase all instanses (form1 >> form5)?
What is developer recommendation for merging projects?
