Indeed, currently there is no delete option for workspaces attached to articles. They are quite locked. In future, however, that will change, we have plan to allow more flexible management for workspace-article connection. As for zips, Chris would need to speak about it, but as far as I know they expect you to keep the top-level folders (zips are created from them) untouched, if you have modified the folder structure on the top level article code might have problems figuring out how the zips should be created. When you have initialized git repo and you want to start over with different content, it is technically possible (as git is quite flexible here), though not really recommended, as it would require so-called history rewrite. I.e. people who already fetched out your git repo into their machines will have problems when you erase the history from server and replace it with different commits. Unfortunately thats the only help I can provide you at this moment. If you have some specifics, though, we'll try to push it forward. Like, which repo/zip is causing the trouble? What would you like to have instead?
