Why don't you make a better debugger than STM-STUDIO?

Some time ago I tried your STM-STUDIO: I found it very rough and can only be used for laboratory debugging.Why don't you plan to build a more flexible debugger that can then be used by the end customer to view internal data or change parameters?If yo...
