The modes (target cpu, OS, debug mode, binary name ?) are a characteristic of a project not a lazarus install. So, its a case of having to do them again for a new project. Might be nice to have a script that did create a predefined list of modes for a new project I guess ....
I have 23 build modes for my main app, really would not want that replicated for every other project I start.
