SimpleUndoClose is a Chrome add-on developed by blandLIFE.dev. It is a simple and minimalistic popup that allows users to undo closed tabs. It is a fork of the Sexy Undo Close Tab extension, but with a more streamlined and straightforward design.

The add-on provides basic usage functionality. Users can click on the toolbar button, and a popup will appear showing the list of closed tabs. They can then select the closed page they want to restore. Keyboard navigation is also supported for easy navigation. The add-on also offers a delete button at the lower right corner of the focused blue for deleting individual entries.

One important note is that SimpleUndoClose does not restore tabs with their tab history. If restoring tabs with tab history is a requirement, users can check out SimpleUndoRecents, another add-on by the same developer.

SimpleUndoClose retains the features of the Sexy Undo Close Tab extension and also introduces a few changes and new features. Users now have the option to set the page title instead of the URL as the tooltip. The UI of the popup and options page has been reworked for a better user experience. Additionally, there have been code reworkings to facilitate the upgrade to manifest version 2. The add-on also supports keyboard navigation and is free from any ads.

Overall, SimpleUndoClose is a useful tool for Chrome users who want a simple and efficient way to undo closed tabs. It offers basic functionality without any unnecessary frills. Users should note that the add-on is still in version 1.0, so there may be some bugs that the developer has missed. Feedback and bug reports are appreciated to improve the add-on further.
