Purposes to have special Journal plugins API instead of regular activities:
The reason to this feature is having Journal views for different purposes i.e. Journal plugin could be very common/simple but views for Books/Video/etc could have some special UI features. Another benefit of Journal plugins is that we can have non-core plugins and distribute them from ASLO.
Purposes to have special Journal plugins API in addition to activities API:
* security reasons, browsing Journal entries and launch/remove/change objects could be denied for regular activities in next sugar releases
* security reasons, browsing Journal entries and launch/remove/change objects could be denied for regular activities in next sugar releases
* Journal integration
* Journal integration
** fast access to plugin views
** ObjectChooser integration
Plugins API will provide necessary functionality:
* TreeViewModel as a source of objects; so, all pulugins should use TreeViewModel for list widgets
* TreeViewModel as a source of objects; so, all pulugins should use TreeViewModel for list widgets
* UI widgets, like TreeView, TableView, tag clouds etc.
* UI widgets, like TreeView, TableView, tag clouds etc.
* shell related procedures(like activate objects)
