Popup menu in the top bar to easily manage snap tasks (list, changes, refresh, remove, install...). Update notification at session startup. All the results of actions are displayed in GNOME Terminal, so you can exactly know what you are doing and what is processing. Very light extension, no background process, no periodic background task. You can turn off refresh check and associated notifications (just a variable to toggle in <extension_folder>/extension.js). This is not an official Ubuntu/Canonical extension.
