Thank you kind words about Uninstalr, we're very glad you like it! Your suggestion about adding an option to skip registry cleaning is valuable, if our main developer will consider implementing a checkbox or a similar feature to allow skipping registry modifications in a future update, may we ask, in the meantime, why you'd prefer to skip registry cleaning in some cases? Understanding your use case better would help us prioritize and design this feature. Also, please remember, after you select an app to uninstall and click the Uninstall button, you are free to edit the items that Uninstalr says it will remove, for example, you can edit the "Software's registry data: " area in the uninstallation screen prior to starting the uninstallation process.
