Ah, OK. I will add them in my config and call it a day. ;-) >> 3. The image sizes of the same latex environment (e.g., \[ \]) is >> different for different formulas.

No, AFAICT I don't see the issue with png previews. However, all latex previews, \( \) and \[ \], seem to be of the same size now. >>> If you do come across any issues, please let me know either in a reply here >>> or >>> the org-mode matrix room.
