Improve blocks / pages relations
Now we only have a way to setup pages where a block can be displayed. Sometimes you might need to configure a block for all script pages except specific page(s). It's possible to set Sticky to OFF and set it for all the pages where you wish to have it. But, that's a bit incorrect way - this block will not be displayed on some other pages, that are added later. Every time I install a new plugin/package I'll have to check new pages for that block to have my block visible on them.
Here is the suggestion - add extra functionality that'd allow to configure a block for Allowed or Sticky Pages minus Blocked pages. That would be a great addition to make blocks management even easier.
