Some ideas for improvements

• Need a data accessor for mounting large datasets (folder).
• Pop-up warning window for delete option.
• Remove caches since we have direct access to files now.
• Need a color_generator() to generate a new color that has the most contrast with the existing colors. The default four colors have two very similar.
• Better label logic? or show an instruction panel.
• Need to support multiple labels per image. Currently, thumbnail cards can only display a single color corresponding to the fist label.
• Allow users to improve/modify labels later. Use SplashML to store labels and SciCat for bookkeeping data.
• file manager to navigate list_matrix files.

• Need to allow users to de-select wrongly colored images in the pop window.
• Remove Label button.
• Fix the multiple color display and use label button for both label and un-label.
