Hey bud! :)
The first issue is not related to the newer versions; it's just the text removal algos not being able to handle that case. I think is being filtered out early on in the process and is discarded. Thank you for reporting it eitherway, it's good to have something to works towards, either by creating a different algorithm or by improving the existing ones to handle it.
The second & third are most likely related. I made an effort to normalize line height/vertical spacing between text, for all fonts, which was to be expected to bring out some bugs. 'Attempt text centering' was never actually meant as a real feature toggleable feature, it is a remnant of an algorithm that I figured didn't really work properly, so I made it optional for edge cases when people absolutely want to try to centre text. I'll definitely have a look at it though, I think I know of a way to make it centre properly, without having to guess if it should or not, which is the current implementation.
Thank you very much as always! :)
