Should remember settings for each site and page Rated 2 out of 5 stars

For each site and each page, the addon should manually run to colorise the page. Even within the same session, if the page is refreshed we need to run the addon again. Making it virtually useless and just a waste of time. If you are not playing with site colors, please stay away from this addon until it remembers the settings.
On a positive note, its colorisation has better results (especially complicated sites like youtube). It would be better if there were some presets (with different color filters that we can try). Also there could be an option to go back to default state.

Edit: Answer to the developer comments below: I never ordered you to do any of the changes. I said my opinion and added my suggestions. That is what a review is for. And no need to ask MS/Google, there are far better addons here that fit my requirements.
At the same time, I understand the wonderful work addon developers like you are doing. I appreciate and admire you. But that does not mean we have to accept whatever you do or always comment positively. You have ur freedom and I have mine.

This review is for a previous version of the add-on (3.0). 

Site-specific automation is on my wish list, but I will not invest my time into this if the potential user base proves too small.
You may of course give your opinion, it is just that I think there is little reason to advice against the use of an add-on that has unique features and does exactly what it promises to do.
