Having something digital to substitute the whiteboard would be fantastic. Not just for designing the pipeline, but also for seeing the results of an actual run of the pipeline.
I believe one thing that cause it is changing a repo from private to public without unchecking Pipelines permission (enabled by default). The new GitLab profile pages looks absolutely gorgeous, but I suspect many will be turned off by the highly visible 'build: failed' icons next to the repos, even if those repos contain nothing but a JSON file.. I personally had to resort to deleting the repo and creating a new one to get rid of it. And on that note, clicking on the '/users/username/projects?limit=10&page=2' next button results in the Overview tab turning blank.
The profile page, however, doesn't seem to update. My guess is that it's a caching problem. I've logged https://gitlab.com/gitlab-org/gitlab-ce/issues/52780 for this.
Implementations of workflow languages optimised for compute performance (e.g. using JIT compilation) do exist, but are not widely used outside of situations where the workflow combines both compute-intensive work and coordination of external tasks.
The Actions UI is going to be huge for user adoption.
I can't say how many commits I had of various .gitlab-ci.yml files with just tiny changes in each one.
