After extraction there is a wait before Keka closes.
Perhaps this: #224 (comment)
This is a feature, Keka waits for the notification to close, so in case you click on it it can show in the finder the extraction/compression files. This is a 5 seconds wait.
I find this wait annoying, waiting for my finder window to regain focus so I can work with the extracted files.
Any chance there can be a hidden pref to disable it? So Keka closes immediately after extraction is finished.
Thanks!
