Regarding the questions:
1) Is there a way to reset the fieldrenderprops so the form sees it as having not been modified or touched - Currently, they will be updated as the field value is indeed modified. If we do not change it, this can lead to wrong information in many cases.
2) Is there a way to use promises or something like that to detect a successful form save in order to disable the save button - The Form save (the request to the server) is made by the developer, which means that the developer can use the callback from the server. The KendoReact Form is not making requests to save the data internally, this is why we have no information when the Form is saved in order to provide such a callback.
In general, we recommend submitting new tickets/forum posts for different questions as for example someone may be searching for the same answer, but it will be difficult to find when it is answered in a different topic.
