I thought it would be so good if it were possible to optionally right justify From and Correspondents columns. Particularly in Dark Mode, which I prefer most of the time as it's easier on the eyes; with lots of emails from various sources, I find it all a bit of a blur. I think this is partly to do with the Font thickness. In Mac OS system dark mode, the font in the columns seems too bold. It's the same in light mode, but bold seems ok with black on white, whereas in dark mode, white text on black background perhaps could be lighter, or less bold for better visual function.
But with that out of the way, the crux of the matter is that I think it would be much better, easier and quicker to take in visually, domain sources of emails if the list could optionally be right justified, so that common source domain suffixes could be recognized in a list much easier and clearer. This would mean, of course, truncating from the start of lines, rather than the end, allowing for column width. I know that this is basically what the filter function is for but this implementation would allow for quicker sorting and dealing with new emails in particular. It would just be a lot easier to take in visually. Left justification of various domains can look a bit of a confusing mess.
Please say if you also think that this is a good idea. I hope to see this implemented in my favorite email client soon. And I hope that future releases are as backward compatible as possible and as light as practicable. (Still using Mac OS 10.15.x; and some people have their reasons for using older systems than that.)
