Rectangle Selection од bogdys

Select text in a rectangular area, instead of line by line. Sometimes referred to as vertical text selection or a column selector, this extension lets you select exactly the portion of a page you need.

Features:
- Toggle between selecting individual characters or full words. Relevant when rectangle selection only selects part of a word.
- Select while scrolling. Useful when the data you need to select doesn't fit entirely on the screen.
- Optimized for performance. Works even on pages with very large amounts of text.
