Glen Walker (ID: 000000969530acf1) Voted 3 ★ - Updated 09/09/2021 It works but doesn't remember your settings. If I open the menu, select a radio button from both categories (color blindness and vision loss), then close the menu, if I open the menu back up, the radio button choices are not correct. It goes back to "none" for both categories even though the filter is still applied.

Stef Patterson (ID: 0000006cdf9ba9fa) Voted 4 ★ - Updated 02/21/2021 This plugin has come in handy when testing websites. I agree with another reviewer that being able to move the menu as well as keeping it displaying even after tapping on page. Update these two and I'll update my review to 5 stars.

Andrei Katukhin (ID: 0000001e92ad737c) Voted 4 ★ - Updated 09/20/2019 Works for most web sites I tested and even mockups (e.g. Invision). One annoying thing is that you can't move menu which overlays part of the screen - pls fix to get 5 starts :)
