1)You could see the list of all registered services :
just go to "Search" section, then click the "See All" button.
2) A tag cloud could be a great idea
. Not planned for the moment
3) For the moment, Petals Master doesn't provide a user right management on resources (services, WSDLs, endpoints), but only on action (View/Edit...). So you can't restrict access right to a particular resource for a particular user. You could only configure access rights to allow a category of users (linked to a role) to View or View/Edit all services for example. Fine grained access rights is planned for the moment.
1) Indeed, but this is just a workaround.
It is not a real "Browse" action.
3) Whatever, I don't think it is an urgent need.
I was just wondering how a "Browse" action could apply to other stored items, such as organizations and persons.
The browsing main target would be services.
