Switch easily between opened tabs using thumbnails made from screen captures of the pages. The extension gives as much scree space as possible to the thumbnails. If you only have one page opened, only one thumbnail will fill the entire screen. If you have 10 tabs opened, the screen will be divided in 10. Usage: Click the extension icon on the top right to see the thumbnails. Then click the thumbnail to navigate to its corresponding tab. Alternatively, you can use the hotkey Ctrl+M (while holding Ctrl press M) to open the thumbnails. If the hotkey doesn't work, go to chrome://extensions/ and scroll to the bottom right and click on keyboard shortcuts to set the shortcut manually. Notes: After installation, the extension will only work in newly opened tabs (won't work on pages that were opened before you installed the extension). Chrome only allows to get screenshots from active tabs (tabs you have seen). If you open a tab with Ctrl+Click, the middle button of the mouse or selecting "open in a new tab", there won't be a screenshot, but a thumbnail with the url (once you navigate to the tab or "see it" for the first time, the screenshot will be created). The thumbnails are made in a high resolution and medium compression setting to maximize performance. In most cases (many tabs opened), the artifacts of compression won't be seen and less resources will be used generating the screenshots. Known issues: Chrome doesn't allow extensions to work in some pages (the webstore, the new tab page, etc). In those pages, you won't be able to see use the extension to view the thumbnails.
