Syntax: !req EPISODE [quote or timestamp] (max. 8 square brackets)
For quotes, now you can request by index (e.g !req Chobits 1x17 [10-11]; !req Chobits 1x17 [20] [24]). Keep in mind, though, that index numbers might change at any time.
You can also generate a copy command with the quotes. Hover the desired subtitle and enter the amount of lines you want to copy.
