- fixed user styles in base theme
- added new divs for better control on user profile and user index pages
- reduced data on course user profiles down to minimum
- removed user/tabs.php completely and all uses of it
- changed default user icon pix to something very bland (bye bye smiley cake)
even non-course and sticky blocks.
The parent context is block_instances.parentcontextid.
The block context should be used for checking permissions directly
related to the block, like moodle/block:view or moodle/site:manageblocks.
However, if the block is displaying information about the current page,
for example the participants block showing who 'here', then it may be
better to use the context of the page where the bloack is appearing -
in other words $this->page->context - to check permissions about the
user's ability to see participants here.
Or, if the block is displaying something stronly related to courses,
for example, a course meny block, the block should probably use the
context for $this->page->course to check permissions.
That was becuase not enough information was being passed in for the blocks editing controls to construct the right URL to reload the page.
It is also now possible for admin external pages to add some UI next to the turn blocks editing on/off button. For example, when you are editing the list of course catgories, the turn editing off button is now in the right place.
