Allow Replace Functionality Directly from the Ctrl+F Search Dialog

Currently, pressing Ctrl+F opens the search dialog, while Ctrl+H opens the separate “Find and Replace” dialog. It would be more efficient and user‑friendly if the standard Ctrl+F search window also included an option to replace text, similar to how many modern editors combine both features in a single interface.

This would streamline the workflow by reducing the need to switch between two different dialogs, especially when the user starts by searching and then realizes they need to replace something. Ideally, the search window could include a small toggle or expandable section for replace options.
