After a cursory glance at the features of the extension it works really well. There's nothing I'm particularly bothered by, particularly the easy of customisation, however there are some features defaults that I'd prefer, namely:
1. differentiation between shorts and playables (I'm not opposed to shorts in my feed though I absolutely don't want playables).
2. Don't hide thumbnails by default (I use the thumbnails as a large part of whether I will watch the video, it's really easy to change the setting [3 clicks] but I still think it's a somewhat odd default)

Overall good extension that does as it describes and is easy to customise. I haven't looked into the security of the extension yet, which is always an issue for less rated extensions, but from the cursory glance I would recommend it's features.
