My suggestion is to have some tags be in different colors or to have the ability to have specific tags in different colors. For example I want to have R-18 and sexual related tags be in a red color so that I won't accidentally miss them and they'll be easier to see. This is more of a quality of life change rather than a necessary one but I feel like it's a good idea that should be worth considering. Another idea is to be able to hide certain tags that usually spoil the plot like who falls in love first, or "multiple reincarnated individuals".
