the implementation is great. the design can be a bit better

I understand from an online review of this extension that there should be a steering wheel icon in the toolbar to access the extension. I am not seeing the icon, and trying to manage the extension via my extensions list does not provide a way either. There are no instructions on this extensions web page about how to use it.

What am I doing wrong? And can you please provide some instructions or at least a screenshot?

Wonderful!This is just what i need!

しばらく前から、スクロールする量が不安定になっています。設定値の倍ほどの距離をスクロールしてしまう状態になることがあります。
下方向がおかしい場合はページの下端まで、上方向がおかしい場合はページの上端までスクロールすると（そのページに関しては）直るのですが、あまり実用的な対処方法ではありません。

For all your work ....

Thanks for the update. It works again. but step size 300 is too small for 4K screen. Could you kindly increase the size, like 600, 1000? Thanks.

It is suprising how this nicely tuned piece of code survives to this day. Thank you kataho.

Smooooth as silk.
