Re-newtab is a Chrome extension - A redesigned, productive and pragmatic new tab alternative. You can install it from Chrome Web Store. Privacy see here.
This extension provides 19 desktop widgets, plus bookmarks manager, history manager, extensions manager, downloaded files manager and quick search function in your new tab page (so chrome will show you these permissions when you install it).
The core idea of this extension is to help user quickly find web pages that you want to open. The home panel shows links, information and functions by different widgets. Of course, you can customize these widgets. Sometimes if you just want to see a wallpaper on new tab, there is a wallpaper mode that hide all elements on the page and only show the wallpaper and a toggle button.
You can use keyboard shortcuts to search for bookmarks, history, opened tabs and downloaded files, similar to Alfred.
Home panel contains many versatile widgets(cards), like clock, calendar, recently closed tabs. You can add/remove widgets, drag and drop widget to a new position, change widget's title and color.
Main widgets:
Bookmarks are an important concept, because they are your own collections and what you need. This extension provides a more productive bookmarks manager.
Similar to Mac Finder in columns view, you can manage and navigate bookmarks by mouse or keyboard shortcuts, for example:
Search or clear browsing history by date range.
Show your downloaded files. You can open downloaded files or open their folders, and clear download history.
Show synced open tabs on other devices.
Manage all extensions and apps. You can enable/disable/remove the extensions and open their options.
