In the page to select functions from base classes to override in the newly created file the loading of the base-class information can take quite a while. This is currently completely invisible to the user, it looks like its just broken until the parsing in the background has finished. Just showing a progressbar or a single item in the view 'loading base class information' would already convey to the user he has to wait a bit and be patient. Reproducible: Always
