When showing all apps, hides apps from the system category. Apps can still be accessed by selecting the system tools category. Basically made redundant for 3.8+ with the introduction of app folders, so it won't be updated.
Note: Binary files aren't shown on the web site. To see all files, please download the extension zipfile.
Uhm... System Tools is not necessarily the last category, it depends on localization, so this extension is wrong.
I thought about that, but thought getting it by name would cause more issues with localisation. How can I get the System Tools category reliably?
