From an answer on another question:
If you have chosen Precision because it is minimalist, then you might want to consider adding the 'Panels Everywhere' module. This module works very well with Panels (same authors) and allows you to bypass the Drupal Theming process altogether. This greatly simplified my styling work.
Does this mean regions and blocks are completely ignored with Panels Everywhere (PE) in favor of panels only?
If so, does it mean one has to recreate some layout for standard pages such as node edition and publishing for example? I have an editor user profile to create specific content. Do I loose all the layout of existing Drupal screens the user could access?
After enabling PE, what configuration is expected regarding layout and theming (CSS) on standard pages delivered by Drupal?
Fact is, when trying PE with the Precision theme, I lost layout on all standard pages, but I want to know if this is a configuration issue or not.
