Would you be interested in having a simple multi-line alignment for sf::Text?
You may or may not have already seen this:
https://github.com/Hapaxia/SfmlTextAlinewhere I created something similar to sf::Text that also included a multitude of alignment features.
However, I'm proposing a simple "Left/Center/Right/Justify" choice that would simply affect the entire text globally.
Maybe not even justify if you'd prefer not to have that since it would depend on the type of justification you'd want: "word" justification or "character" justification where "word" only stretches spaces and "character" also separates characters. Of course, you could have both as an option.
The left/center/right option is pretty simple to implement so I'd guess you'd prefer that, if this is a consideration at all, of course.
Let me know and I'll start up a draft...
