Custom Tkinter Text Box Widget with Word & Line Highlighting

[vishal24102002]

I have an idea for a custom Tkinter Text widget that allows users to highlight not only specific words but also entire lines with different colors.

This would make it easier to emphasize important text, keywords, or log lines inside a simple text box. It could be useful for note-taking, log viewers, or code editors.

Would this be a good feature to add as a custom widget for Tkinter?
