form_filler_ui.py

Tkinter UI + Playwright browser helper that types your chosen text into the
currently-focused field in a browser page at a configurable WPM.

Workflow
1) Enter URL, text to type, and WPM in this app.
2) Click "Open Browser".
3) In the browser, click/focus the target input/textarea/contenteditable field.
4) Trigger typing either by:
   - Clicking "Type Now" in the app, OR
   - Pressing the in-browser hotkey: Ctrl+Shift+Enter (configurable in code)

This uses Playwright to generate DOM keyboard events in the page (not OS-level
keystroke injection). Intended for websites/apps you own or have permission to automate.

Install:
    pip install playwright
    playwright install

Run:
    python form_filler_ui.py
