Feature description

I would like to suggest adding a "Recent" or "Favorites" section to the top of the language selection dropdown. Currently, the list is purely alphabetical, which requires constant scrolling to find frequently used languages.

Use case

I frequently translate between Turkish, English, and German. Since the language list is quite long, scrolling to find these specific languages every time creates a significant friction point in my workflow.

As seen in the native Apple Translate app (attached in the description), having the most used languages pinned at the top allows for much faster switching. This feature would be a huge time-saver for polyglots or anyone working in multi-language environments.

Proposed solution (optional)

Add a "Pin" or "Favorite" option in the settings so users can manually choose which languages stay at the top.
