나은 다나와 is a free Chrome extension developed by Sin Jeong-hun. It falls under the category of Browsers and is specifically designed as an Add-ons & Tools subcategory. This extension aims to address the inconvenience of using the 다나와 website.

One of the main features of 나은 다나와 is its ability to assist in checking search options. When there are numerous options to choose from, it can be extremely inconvenient to manually check each one. For example, if you are looking to buy a laptop and want to select all laptops with a resolution of 1080p or higher, the current 다나와 UI requires you to manually check 21 checkboxes, which is a tedious task. Furthermore, if you want to undo this search condition, you need to manually uncheck all 21 checkboxes again. This extension provides an easy solution to this problem. Simply check the two resolutions you desire, such as 3840x2400 and 1920x1280, and then click the "~" button to automatically check all resolutions in between. If you want to remove all 21 checked resolution options, you can simply click the "" button to uncheck them all.
