Feature Request: Stretch the cursor to the tab width

Thanks for the wonderful plugin.

It would be nice to have the cursor stretched to the width of the tab character or the glyph underneath.

Something like the one below from kakoune editor

Oh wow! That would need to significantly change the way smears are rasterized (and it's already a hacky mess 😆). I'll keep that in mind for the day I need a good challenge
