Select applications or cluster scope in the Cluster creation form
In the CI/CD > Clusters creation, you can specify only cluster parameters. Only after the cluster has been created, you can go and install applications (tiller, ingress, ...). It would be helpful to avoid this step and already select applications you want to install in the creation form as an additional way to make the flow easier.
Add the ability to define which applications you want to deploy to your cluster after the creation. They will be automatically installed in the same way they would be when clicking on the application buttons in the cluster details page.
As a possible improvement, use "scopes" (e.g., auto devops, monitoring, runner) instead of single applications when defining what you want.
