Hello. I have been developed chrome extensions. I can build the extension for you, Sir.
The extension will be executed to click a specific button on a time the user set before.
To put specific time on the window, popup page is needed to build on the extension.
When a user set a time and waiting at the page then a button should be clicked on the time on the tab.
To click a specific button on a specific url, the url should be allowed in the extension. Clicking a button script will be in contents script in the extension which is executed when the extension allow at specific url. Then the extension will run.
To build the web, I want to ask about keys on a dashboard. Specially if the keys give users access executing the extension from an administer or what.
