[Feature request] Custom tab character (\t) render width

[Anixias]

Is your feature request related to a problem? Please describe.
The render width of the tab character (\t) is 5. I have never met anyone who uses 5 for their tab width, only 2, 4, and 8. I would love to be able to change this to 4. Note that using the 4 spaces on tab setting is not a valid solution, as I would like to keep the \t character instead of spaces.

Describe the solution you'd like
Added a setting to specify the render width of the tab character (\t).

Describe alternatives you've considered
You can opt for using spaces instead of tabs, but this is not a valid solution to the problem.
