📄 Description

Summary

Enhances the text input experience by adding intelligent height management and scrolling capabilities.

Features

  • Natural growth: Text input expands from 1 to 10 lines as you type
  • Fixed height with scrolling: After 10 lines, maintains fixed height with internal viewport
  • Interactive scrollbar: Visual scrollbar for navigating long text
  • Automatic cursor tracking: Cursor stays visible as you type or navigate
  • Keyboard navigation: Page Up/Down support for scrolling through content

Benefits

  • Better UX for long messages: No more endless text box growth pushing chat history off screen
  • Familiar behavior: Similar to other modern chat applications
  • Maintains context: Can see chat history while composing long messages
  • Visual feedback: Scrollbar shows position in long text

Implementation Details

  • Enhanced textarea.Model with MaxHeight and viewport scrolling
  • Added scrollOffset tracking for viewport behavior
  • Implemented ensureCursorVisible() for automatic scroll adjustment
  • Scrollbar appears/disappears based on content overflow

Test Plan

  • ✅ Type more than 10 lines of text to see growth limiting
  • ✅ Verify scrollbar appears when content exceeds visible area
  • ✅ Test cursor stays visible when typing at bottom
  • ✅ Confirm Page Up/Down navigation works
  • ✅ Check that chat history remains visible

This is a reopened PR after resolving merge conflicts with the latest dev branch.
