Is it possible to change XE5's workspace to Delphi 7 like? Designing Forms inside a window is really pain and i would like to move components palette to up and design form outside of a canvas.

You can switch to the Classic Undocked desktop in the desktop drop down. It's not identical to Delphi 7, but it is possibly as close as you'll get out of the box.
The other thing you can try is to enable the floating designer, disabled by default. More details here: http://francois-piette.blogspot.co.uk/2013/04/enabling-floating-form-designer-in.html
You'll need to adapt the registry key to your version. The article has the key for XE4. For XE5 it is:
HKEY_CURRENT_USER\Software\Embarcadero\BDS\12.0\Form Design
Set the Embedded Designer value to False. Restart your IDE and you've now got a familiar floating design surface.
