Now you can create a new task scheduler for each one of the 79 tools and run it when you need to. For example, I chose from the list above.

Note: Remember to run every new task as root.
Note: Uninstalling the Diagnosis Tool is child’s play. Go to Package Center, click on the installed packages, go to Diagnosis Tool and select Uninstall.
Note: If you are comfortable with SSH, then just login and execute:

>> sudo synogear install
password: [enter your NAS password]
download DiagnosisTool 4.0.0-4121 successfully
(synogear) >> iotop
ctrl-c to stop
(synogear) >>
cltr-d to return to user prompt
Actual prompt >> depends on user settings.
Next time the fastest way to use tools is to type "sudo synogear install" 
again, will update if update available and then give you "(synogear) >>" prompt.
