@davidAlonso:
In addition, in my opinion it would be great to have a more modular design. For example, have options to completely disable network components or storage components to reduce compile times.
I agree. Fortunately, the design is already modular in some extent. At the present we can use the .mbedignore file for some sort of configuration (an example is available here). Nevertheless, it would be nice if we can include/exclude the modules using the mbed_app.json configuration file.
