LSPRO parental functions
You can enter the pin in the settings. After you entered the password/pin, you can enable disable by right clicking anywhere on links or sources list. After that, if the entry contains
<parentalblock>true</parentalblock> and Parental Block is enabled, it will not appear on the list.
After enabling or disabling, please move one step back so that the screen could be refreshed.
I will see if blockpin could be enabled easily in near future.
