I would prefer that the extension would have a manual timezone option, where one could select, at the very least the standard UTC-00 option.
As well as an auto timezone sync. Google and Reddit both block me if my timezone does not match my IP address and if you would be able to fix that I think that would be spectacular. I do not expect you to solve my issues for me but I am explaining that their is a use case that exists.
I think it runs great, and it is coming from a more trustworthy source which I like, but even adding a manual option would be a great improvement. I have more quality improvement suggestions, but will reply when I remember them.
