The editor modal is resizable for convenience. Any file can be renamed in-place via a dedicated “Rename” action, without needing to open or re-upload it. -- **Batch Operations (Delete/Copy/Move):** - - Users can select one or many files and perform batch actions: delete files, copy them to another folder, or move them to a different folder. Action buttons for these operations remain visible whenever files exist and become enabled only when one or more files are selected. + - Text-based files (e.g., .txt, .html, .js) can be opened and edited in a modal window without leaving the page.
