Give users a way to select what they see and where in the BO
The views and content blocks in the BO (eg. Order page, Customer page, ...) are fixed by design and are the same for all users, even if it doesn't fit their needs.
As a user of the BO, I would like to be able to select what block I see or don't see, and where block are displayed on the page (order and position in columns/grid). Depending on how I use the BO, Users don't all have the same need in term of information and they should be able to customize that.
Please note that this is already possible to do that in other CMS for a long time ago.
