I recently realized that in some cases youtube.com's search results are better for me cause it obv knows which channels I subscribe to. So wanted to import my subscription list to Kagi but noticed there is no csv uploading option like there is for personalized domains.
I assume this has something to do with the specific method that channels are being stored that just dumping urls wouldn't work as they need to be converted to channel id's (in youtube's case) or something. Hence why it takes some work to implement this.
