This is more of a feature request than anything, however, can actions such as Optimize Database and Clean Bundles have a popup similar to the Empty Trash action? At times I find myself wondering if the action even worked as there is not an indication of such, short of the swirling around the Activity button on the WebUI.
A bit of uniformity could go a long way with things like this.
Not to suggest that your request isn’t worthwhile, but if you initiate them from Settings -> Troubleshooting you should see completion messages for both Optimize Database and Clean Bundles:
Indeed, however, for the sake of uniformity, it would be nice for it to show a popup like the Empty Trash option does. The idea that the others simply cease to give feedback when done could lead people to think there was an error or that it did not complete successfully, especially when the logs might have an error when the actions are running.
