Feature Request: Auto-restore the last opened script on launch, and improve Chinese support (input, word tracking, and UI localization)

[TCC-icdat]

Feature Request 1: Restore last opened file on launch

Problem: Every time I launch Textream from the Dock (not by double-clicking a .textream file), it opens a blank "Untitled" editor. My previously saved scripts are never auto-loaded, so I have to press ⌘O and navigate to the file every single time. This is very disruptive for a teleprompter workflow, where you often quit and relaunch the app between takes.

Suggested implementation:

• Persist currentFileURL to UserDefaults in saveToURL / openFileAtURL (e.g. key lastOpenedFileURL), and restore it on app launch — either by auto-opening it or by pre-filling the editor.
• Alternative: on launch, check NSDocumentController.shared.recentDocumentURLs and load the most recent .textream file.
• A setting toggle like "Restore last script on launch" (on by default) would be a nice touch.

Feature Request 2: Chinese (Simplified) support — input, word tracking, and UI localization

Problem: As a Chinese user, I currently face three blockers:

1. Cannot type Chinese in the editor. I can only paste Chinese text in; direct Chinese IME input doesn't work properly (related to Cannot input Chinese #34).
2. Word Tracking / Voice-Activated modes are broken for Chinese text (Word Tracking & Voice Activated broken for CJK (Chinese/Japanese/Korean) text #60). This is the killer feature for Chinese streamers and presenters, and it's unusable for us right now.
3. UI is English-only. There is no Simplified Chinese localization.

These three issues together show that the Chinese-speaking user base is real but underserved. A Simplified Chinese localization, plus fixing CJK word tracking and IME input, would make Textream the go-to teleprompter for Chinese users.

For context, I'd love to recommend this app to friends, but the current state makes it hard.

Thanks for the great app — it's genuinely the nicest free teleprompter on macOS!
