Describing all functionality without using too much jargon in a paper is a challenge. Understanding the work of others is even a bigger challenge. We have witnessed some confusion about the Midas framework in some papers and would like to clarify them on this page.
Midas inherently supports multiple users (in contrast to what Julia et al. states). It is even one of the core features to support concurrent interaction. To better position the  paper, the authors can claim that Midas does not provide a lot of constructs to deal with conflict resolution besides:
Spano et al. argues that Midas is affected by `spaghetti code` because it integrates UI components within the gesture definitions. However this integration is fully optional but very beneficial to describe certain complex gestures. In the Midas paper we actually describe the spaghetti problem as a case where multiple gestures definitions are interwoven in order to provide a form of conflict resolution. These implementations can for instance be found in the Android framework.
