Future Features that are in discussion and will come in future.
Data Connector: More sources
Currently Data Connector on skybow's Modern Forms supports SharePoint libraries from other site collections as source for a lookup control ("Cross-SiteCollection Lookup").
More Data Connectors to connect and select data from other sources than SharePoint is high requested in business cases. Therefore we're planning to implement other connectors (and controls) to bring that functionality to Modern Forms.
Package & Publish: Support server 2019 for modern solutions deployment
Since SharePoint Server 2019 as well has the Modern Experience, Solution Studio will provide the functionality to deploy Modern solutions built on SharePoint Online to SharePoint Server 2019.
More Modern Forms enhancements
Field label configuration, Conditional Formatting on fields and controls, different forms per Content Type, possibility to embed Modern SPFx web parts.
Organization: User Management
Use Organizations and Groups to structure your teams working on solutions in Solution Studio. Create an organization and groups to define people that are working on the same projects or in the same department. Sharing of solutions and SharePoint tenants within your groups is pretty easy then.
Organization: Dashboards and Portfolio
Have an overview of running licenses and deployed solutions on environments in handy dashboards.
