Might be too late to put this into the current version but I thought it might be a good idea to have an extra field in all the elements (Resources, Snippets, Chunks etc) where the developer can put in notes such as todos (A good example would be ‘Change path to live site’) while working on the site.
All of these notes would be visible from the dashboard so could be run through as a checklist.
There’s no easy way to do this in MODX that I know of in the same way you could do when creating something in an IDE.
