Software tools are being used by experts in a variety of domains. There are numerous software modeling editor environments (MEs) tailored to a specific domain expertise. However, there is no consistent approach to generically synthesize a product line of such MEs that also take into account the user interaction and experience (UX) adapted to the domain. In this position paper, we propose a solution to explicitly model the UX of MEs so that different aspects of UX design can be specified by non-programming experts. Our proposal advocates the use of multi-paradigm modeling where this aspect of the design of an ME is modeled explicitly and adapted to a specific user expert.
