Updating

To check if you are running the latest version open the settings. If there is an update available you can press the button to download and install the newer version.

For better search results ueli is keeping track of the applications, files and folders you are executing. All information is stored in ~/.ueli/ueli.count.json. If you don't want ueli to track your executions simply delete that file's content and disable logging via the settings.
