It would be a good idea only to the extent that we do not add new stops.
None of the possibilities listed in the question, except the food related items, are of interest to me. They're too limited in their offerings and will therefore be high-priced to sustain themselves, making them even less interesting to me. Please make decisions about what goes in these storefronts based on usefulness (e.g., dry cleaners, shoe repair/sales), broader appeal, and sustainability, if possible. And look to areas that are well developed and have offerings well used by the neighborhood. Look to Shattuck in Berkeley, North of University, for example. Or College Avenue in Berkeley around Ashby.
