One click to add and remove notification

Monday 29 November 2004 4:06:55 am

Now if you want to remove a node form the notification you have to:
1) go to the /notification/setting page
2) select the node you want to remove
3) click delete
4) click store to be sure...
5) click a link to return to the site

Replace the template
design/standard/templates/toolbar/full/notification.tpl
with the following and for each node you get the button "Keep me updated" or "Remove"

Please note that a there is bug related to this code:
http://ez.no/community/bug_reports/node_not_set_and_fatal_error

Now it works once every time you clear the cache.

Let me know it was usefull.

Tested only with 3.5.0rc1, may works with 3.4.4, earlyer needs
at least a workarond for {set scope=root subscribed=true()}.
