User Reviews

Simple but it works. No extra features, no bloat. Can import/export the list of presets, and it is also available on Chrome. I wish it had a light icon for use in dark theme. I wish it used `chrome.storage.sync` for saving the presets, as that would automatically sync across browsers under the same account.
