It is unclear what this extension actually does. Clicking the task layout button brings up the same dialogue, and same settings, each time. Activating the extension seems to do nothing. Trying to modify the settings seems to do nothing.

Edit: I don't seem to be able to reply to replies. Apologies to the developer, I have zero idea what those instructions mean. I have the TaskviewGridLayout (assume this is what you mean by browserAction buttion) in the Mail toolbar. It does not seem possible to add the button to the Task Toolbar nor the Menu toolbar - no idea if it is one of those that you mean by "over window pages".

This review is for a previous version of the add-on (4.3). 

Hello, Brydie.
1) Please, place browserAction button over window pages.
2) Move to Tasks tab window page.
3) Move sliders, if so, taskview is changed.
Sincerely.
Sungho.
