Save As - Overwrite Protection (Prompt) #168
Description
As it relates to Issues #152 and #153 (Save As overlay), add a feature that protects against accidental overwriting.
On the Save As overlay, when the user clicks the Save As button, the system should always prompt with a confirmation overlay if the filename matches an already existing file in the target folder. The prompt should say, "File 'filename' already exists. Overwrite anyway?" and should have an Overwrite and a Cancel button.
