So, there are basically 2 thing I would like.
1- Option to change the nicknames colors for custom colors. For example, when you select the json file, make it appear a list of boxes with all the colors used for nicknames and be able to change each color for a custom one (maybe in another tab?). So if you use a dark background and there are 100 users with a dark blue color for their nickname, you can change the dark blue color for another easier to read.

2- Options to animate text. For example, an option to make new lines fade in and choose the speed, or come from de side, or push up previous lines, etc... even typewriter effect for each letter of a comment.

Thanks and great job with Twitch Downloader, I use it daily.
