It would be great if it had dark mode

annoying - it opens a popup after installation without the user clicking on anything and without the user requesting to view any page.

works very well and does what it says, might take some learning to understand how it works but after that its amazing. 5 stars

It can not Grayscale mode.
Not found Grayscale button.
No color design.
サイトごとにグレースケール表示をかんたんに切り替えできると思いましたが、そうではありませんでした。
グレースケールボタンはどこにもない。
このアドオンの画面は色彩設計がされていません。目が痛い。

Great Extension! One thing i would wish is a more structured font-management.

it feels pretty chaotic insering all fonts in just one line.
Maybe also integrate custom categories for the fonts.
